I gave my Sexploration lecture at Bucknell University on Tuesday April 23, and there was a huge crowd. I often do anonymous questions at college events where students write their questions on notecards and everyone has to write something, even if it’s “no question.” The anonymity gives folks the freedom to ask their most pressing questions. I only had time to answer about 60% of the questions, so I’m answering the rest here. I’ve combined some questions that are on the same topic.

Is it weird that I want sex all the time even though I’m a virgin?
No. It’s common to have sexual desires regardless of your sexual experience. Remember what I said about the problematic concept of virginity? I encourage you to define sex as broadly as you want and not buy into the cultural construction of virginity.

How often do most people masturbate?
It varies wildly from person to person, and how often just one person masturbates can vary depending on their energy level, desire, stress, opportunity, etc. There are some interesting stats you can check out. In general, I don’t think masturbation is ever a bad thing. Everyone should have a sexual relationship with themselves, and it’s a great way to figure out what you like.

I masturbate so much it’s turned into a chore; any tips for spicing it up?
Masturbation shouldn’t be a chore! But people can get into a repetitive rut. Don’t think of it merely as a quick way to get off, think of it as a date with yourself. Try changing positions, experimenting with new stimulation techniques, adding lube and a toy to the mix.

How long does it take to give a guy a blow job?
There is no set amount of time that it takes anyone to do anything sexual. If you’re giving the blow job, take charge of the situation and do it for as long as it feels good, for as long as you want to. If you get tired or overwhelmed, switch to using your hand or doing something else.

How long should a guy last during a blow job?
I hate to repeat myself, but: there is no set amount of time. Depending on the guy, the stimulation of oral sex could bring him to orgasm slowly, quickly, or not at all. Blow jobs do it for some people and not for others.

How nutritious is semen and how can I convince my girlfriend to swallow?
Semen has little to no nutritional value because you don’t ingest all that much of it. You don’t want to convince anyone to do anything they don’t want to do. You can share your desire with her and tell her why it turns you on, but ultimately, it’s her choice to swallow or not, and you’ve got to respect it. Also, swallowing semen is a riskier practice in terms of safer sex than not swallowing, and I am a fan of condoms for blow jobs.

How do you improve oral sex?
Since you didn’t specify, I’m going to make some statements that apply to all kinds of oral sex (cunnilingus, fellatio, and analingus), then give you some particulars. Enthusiasm, focus, tenacity, and paying attention to your partner’s body language are all good qualities to have when giving oral sex. Use your fingers and hands along with your mouth. For cunnilingus, experiment with different techniques using your lips, mouth, and tongue, and ask your partner to tell you what she likes (if she doesn’t know, explore and ask her to alert you when you’ve stumbled on something great). For fellatio, concentrate on the head and the sensitive frenulum on its underside (remember our anatomy lesson); experiment by applying different amounts of pressure with your mouth along the head and shaft. For analingus, use your tongue and lips to get into the folds of the sensitive anus.

I don’t think I enjoy sex at all. The picture of the vagina (in your presentation) made me squirm, and I have one. What can I do to be comfortable and enjoy the experience when my partner wants to have it?
First, this is a question I can’t answer with a pithy one minute (or three sentence) response. It was a line drawing, but an explicit one, of a vulva, and we are not used to looking at those images on the big screen or in public, so it can make some people uncomfortable for a number of reasons. But you said you don’t enjoy sex at all. Could you be asexual? If you have sexual desire, then it’s a matter of getting comfortable with your body and with sex. Do you masturbate? It all begins there, so I’d start with establishing a sexual relationship with yourself before you address sex with a partner.

What is the best way to have sex in a long distance relationship?
I assume you mean when you and your partner are apart? Use technology to keep you connected. Dirty text messages, naughty instant messages, steamy emails, and Skype with mutual masturbation. I caution you against sending naked or sex pictures to each other, however, since we’ve seen all the trouble that can cause.

Got any good positions?
Each position has its pros and cons, and experimentation is key. If you like Missionary, try Flying Missionary where the person on their back puts their feet on their partner’s chest. If you like Cowgirl, try Froggie where the person on top balances on their feet. If you like Doggie Style, try Tailgate, where the receiver lies on their stomach and the penetrator then lies directly on top of them.

Do you have tips for using a toy to stimulate the G-spot?
Pick a curved toy like Pure Wand, and always aim the curve toward the front of the person’s body. Many G-spots respond to deliberate, firm pressure rather than gentle stroking, so don’t be afraid to apply pressure—just make sure your partner is aroused and ready before you do.

Does size matter?
The easy answer is no. People are way too wrapped up in penis size, when most folks want a compassionate, responsive lover more than a particular size. But I don’t want to deny that everyone has different tastes and turn ons, and some people do like penetration with big stuff. But that’s why God created dildos.

How do I get a vibrator and which kind do I get?
If possible, visit a sex-positive store like The Smitten Kitten, Good Vibrations, or Babeland. When you shop in person at stores like these, the toys are out of their packages, so you can see and feel them, feel the vibration, hear how quiet or loud they are, plus you benefit from the advice of experienced sex educators who work there. If that’s not possible, try one of their websites; they all have detailed product information and customer reviews.

I’m a girl. Do I need to shave my pubic hair before I have sex?
Your pubic hair is your business! It’s a matter of personal taste, just like how you cut and style your other hair. Some people let it grow, others trim it back, and others wax or shave some or all of it off.

As a female, how do you know if you’ve had an orgasm?
I want to say, “Oh you’ll know!” but I want to be more specific. Some of the physiological responses include: a feeling of release; muscle contractions of the uterus, vagina, and sphincter muscles; other muscle contractions and muscle tension throughout the body; involuntary muscle responses that cause you to make strange faces; and cramping of hands and feet. Talking to your peers about what their orgasms feel like is a great way to open up a conversation and hear from real people about their experiences.

How long does it take a woman to climax?
There is no set amount of time, and I hesitate to even say there is an average amount of time. Women often put pressure on themselves about this (I hear all the time “It takes me a really long time,” or “It takes too long”). Concentrate on what’s going on and how it feels, and don’t think about the clock and how you measure up to it.

Do you have any suggestions for mixing things up during sex?
Lube. Sex toys. Role play. Analingus. New positions. Porn. Do anything except intercourse. Mutual masturbation.

Do you poop when you have anal sex? How do you have “clean” anal sex?
When you have a bowel movement, feces stored in the colon pass through the rectum, down into the anal canal, and out the anus. The colon is the storage area, and the rectum and anal canal are pathways. If you have good bowel habits and plenty of fiber in your diet, then there should be very little fecal matter in the rectum and anal canal. When you play with fingers, a toy, or a penis, you’re not going beyond the rectum. Go to the bathroom before anal play. In addition, take a warm, soapy shower or bath before anal sex to make sure your genitals are clean. You can even slide a soapy finger into your anus. Always use the most mild soap you can—either a castile or pure glycerine. A trip to the bathroom and a shower will go a long way toward you having relatively clean anal penetration. I say “relatively clean” because I want you to be realistic. There are no guarantees in life, and some amount of fecal matter may be present in someone’s rectum. If you want to go the extra step to make sure you’re totally cleaned out, you can give yourself an enema beforehand.

How safe is anal sex and how do I avoid anal fissures?
I always recommend that people use safer sex barriers if they are not currently tested and in a sexually monogamous relationship. You can transmit most sexually-transmitted infections (including gonorrhea, chlamydia, syphilis, HPV, genital warts, herpes, and HIV) through unprotected anal sex, especially penis/ass intercourse. In addition, as I said in my presentation, the ass is made of delicate, sensitive tissue which is susceptible to small tears or anal fissures. The best way to protect against them: use gloves to make your fingers butt-friendly, use plenty of lube, focus on warm up and don’t rush penetration, and, as the receiver, listen to your body.

Is it inappropriate to go up to someone and say, “Wanna fuck? Right here, right now?” (I’m female.)
I like people being direct about what they want. I appreciate shameless assertion of your desires. So I don’t think it’s inappropriate to speak your desires in the right context with potential lovers. But, that said, there are repercussions for women who speak openly about their sexual desire, so you’ve got to take those into account, knowing that reactions to your honesty will be mixed (see next question).

How can I, as a woman, express wanting to have sex without looking like a slut?
Just do it. Own it. Don’t let anyone shame you for your sexual desires, experience, or consensual behavior. And don’t shame other women for theirs. Don’t buy into our society’s double standards that applaud men for their sexual prowess and punish women for the very same behavior. (Easier said than done, I know.)

How do we as a society combat false sex information like the “What Not To Do Guide to BDSM,” aka Fifty Shades of Grey?
You’re right, Fifty Shades of Grey is not an instruction manual, it’s a romance novel with some kink thrown in. But lots of people have read it and it’s opened up conversations about kinky sex, which is ultimately a good thing for society. If a friend mentions reading it or being inspired by it, be ready to let them know that it’s not a how-to and have recommendations for other resources that give solid information about BDSM.

I am really into bondage. How do I bring it up to a casual hookup without being scary and intense?
It’s all in the way you present it. Be direct and put it out there (“I want to tie you up” or “It would turn me on if you tied me up”) and make it clear that it’s a suggestion that your partner is welcome to embrace or turn down. If they agree, be prepared to give them information about safety before you start and always use a safeword.

How does a girl approach the idea of being a dominant with a guy?

Why do I have rape fantasies? It feels problematic.
Our fantasies often do not reflect our politics. Rape fantasies can be about exploring submission, masochism, surrender, objectification, control, and a slew of other dynamics. Although “rape” is the hot-button word in this question, the operative word here is fantasy. It’s a fantasy where you create the script, imagine the details, call the shots, and know how it ends—which is an entirely different thing than actual rape.

Any advice for a woman who wants to peg her man? Techniques, a particular toy, a particular position?
Pegging is strap-on anal sex where the woman is the giver and the man the receiver, and it can open up a whole new world of erotic exploration for couples. Great anal sex is all about the warm up. You’ve got to take your time, relish each sensation, and tease your partner into a frenzy before any serious penetration begins. As for toys, I love the Mistress dildo by Vixen Creations and any harness made by Aslan Leather.

What are your thoughts on tantra, sexual ecstasy and spirituality?
That’s a big question on a big topic. More and more people are getting interested in sacred sexuality, the intersection of sex and spirituality, sex magic, and Tantric sex. I want to refer you to two of the best, most accessible books on the subject: Urban Tantra: Sacred Sex for the Twenty-First Century and Tantra for Erotic Empowerment: The Key to Enriching Your Sexual Life.

How do you feel about porn, which often portrays false or fantastical situations? How realistic is porn? Is it misleading?
Well, it depends on the porn! Much of mainstream pornography portrays a fantasy and a performance, so there’s a lot of athletic positions, high energy and high libido, heightened reactions to stimulation, and earth shaking orgasms (both real and performed). You don’t often get to see honest communication, awkward moves, enough warm up before intercourse, a focus on other kinds of sex besides intercourse, partners being shy or quiet, stopping and starting, and much more. I like to portray more realistic sexual scenes in my films, where people verbally negotiate, ask for what they want, use lube and sex toys, focus on activities that turn them on rather than a “script” of how sex should unfold, get into positions that feel good for them, and allow enough arousal time and stimulation to allow female performers to have real orgasms. There are lots of feminists who make porn, and you may want to check out their films as well as films featuring real couples including Make Love Not Porn.

There has been a lot of talk about HPV recently with the release of the new vaccine. But most of what I read for women concerns HPV in the vagina and PAP smears. As a girl who’s way more into anal sex than vaginal sex, what do I need to know about HPV? Can a person get HPV in their ass, is there a test for it, and how is it treated?

–Concerned Anal Citizen

There are more than one hundred types of the human papillomavirus (HPV), and more than forty different strains can be sexually transmitted and affect these areas: the vulva, vagina, cervix, penis, scrotum, anus, and rectum. HPV is a virus most closely associated with genital warts, although not all forms of HPV cause warts. Some of the strains of HPV are low risk and resolve themselves without treatment. High-risk types of HPV can cause abnormal cell growth and cervical cancer. According to Planned Parenthood,

At any time about 20 million people in the U.S. have [genital HVP infections]. Between 10 and 15 million have high-risk types that are associated with cervical cancer. HPV is so common that about three out of four people have HPV at some point in their lives.

The most common way to spread HPV is through vaginal and anal intercourse, but it can also be spread through rubbing, fingering, oral sex, or sharing sex toys. Condoms protect against HPV, but HPV may be present in the skin not covered by a condom, which is why gloves and dental dams should also be used.

Yes, you can get HPV in your ass. If it is a kind of HPV that manifests as genital warts, they can appear in as little as three weeks or as long as six months after infection. The warts begin as small pink bumps that look like cauliflower florets in or around the anus and rectum; they tend to spread rapidly, forming clumps of bumps that may be itchy. The bumps could be painful if they are irritated. Their incubation period is usually one to six months, but they can grow more rapidly if you are pregnant or have a compromised immune system. Remember, in many cases, someone with HPV may have no visible symptoms at all; in these cases, a physician will be able to see them during a rectal exam with an anoscope. Genital warts can go away on their own; or, they can be removed from the skin by applying chemicals to them (usually acids), burning them with an electric needle (electrocautery), freezing them with liquid nitrogen (cryotherapy) or with laser treatment. Even after visible warts are removed, HPV remains in your body, and the warts can recur.

The strains of HPV that can cause precancerous lesions on the cervix can be detected through a pelvic exam and PAP test. If you have HPV in your ass, it’s less common to have treatable precancerous lesions present since there is no cervix or cervix-like place for them to develop, though it’s still possible to have pre-cancerous cells which precede rectal cancer. To test for the presence of HPV in the ass when there are no warts, a physician takes a swab of the rectum and sends it for laboratory analysis (similar to a vaginal PAP test). If you regularly engage in unprotected anal penetration and think you have been exposed to HPV, you can request a rectal exam and an anal papilloma screening (also known as an anal PAP test). If the PAP results come back abnormal, then you should have an HPV test which tests the cells for the HPV virus. If the HPV virus is detected, you can have a colposcopy where they take a biopsy and can look closer at the cells. You can spread HPV from your ass to your vagina and vice versa, so if it has been discovered in one place, it’s advisable to get the other place checked. People diagnosed with HPV should have regular exams to monitor recurrences and prevent complications.

In 2006, a vaccine for girls and women was released that can prevent four strains of HPV: two of the strains account for 90% of cases of genital warts and two account for 70% of cervical cancer cases. The vaccine, currently marketed under the name Gardasil is recommended by the FDA for girls and women aged 9-26. However, women over 26 who have never been exposed to one or more of the strains of HPV can also benefit from the vaccine. Researchers still know much less about HPV infection in boys and men, including its long term effects, risk of cancer, early detection, and potential treatments, although several drug companies are (including Merck, makers of Gardasil) are conducting clinical trials on the vaccination of boys and men.

It’s embarrassing for me to write this letter to you because this is the first time I will admit to anyone that my husband and I have anal sex. I actually am getting past the pain, and learning to enjoy it. A friend told me that you can eventually get colon cancer and other things from letting a man come inside your butt, is this true?

–A Little Scared

Please don’t be embarrassed by your admission and know that there are tons of other people having anal sex out there! Let’s talk about the risks of a man ejaculating inside your ass. The ass is made of delicate tissue that can have minute tears in it, allowing easy access to the bloodstream. If you are monogamous and he has tested negative for sexually transmitted diseases (STDs), then he can come in your ass. If you are not monogamous or don’t know his STD status, then, by having unprotected anal sex and ejaculating in your ass, he can transmit gonorrhea, chlamydia, syphilis, herpes, human papilloma virus (HPV) also called anal warts, HIV, or hepatitis.

There isn’t any definitive link between semen in your butt and colon cancer. However, according to the National Cancer Institute, contracting HPV in the ass (anal warts) can increase your chances of colon cancer. Some studies suggest that other STDs and trauma to the anal canal and rectum — the kind that would result from not using lube or warming the ass up properly — can also lead to rectal or colon cancer.

A new study in Australia shows the risk of contracting HIV while engaged in the practice of topping or taking the “insertive role” in sex. This practice is thought by many to be a lower risk activity when engaging in unprotected sex, but the research is indicating otherwise. How is the virus being transmitted from the receiver to the person on top?

During anal sex, HIV can be transmitted to the insertive partner when a bodily fluid containing HIV from the receptive partner, such as anal mucus, enters the body of the insertive partner. This can occur through the foreskin and surrounding areas, the eye of the penis to the urethra (also a mucous membrane), or through tiny (often invisible) breaks in the skin of the penis.

Anal mucus is increasingly being mentioned in Australian campaigns as the infectious body fluid potentially infecting the insertive partner during unprotected anal intercourse.

This is a significant piece of the puzzle which reminds us about how HIV can be transmitted during unprotected anal intercourse. I recommend everyone read it to stay informed about transmission and share it with your lovers, partners, and friends.

My husband and I engaged in some experimental anal fingering recently, myself being the receiver. While it didn’t hurt, it wasn’t the most mind-blowing experience I’ve ever had either, but I’m willing to give it another try. When I went to the gynecologist recently, she found that I had a very small number of possibly precancerous cells due to a virus. It is similar to the human papillomavirus that causes genital warts, only without producing the wart itself. It’s a fairly minor issue as many women don’t develop anything and can go years even without diagnosis. But, as my doc already demands a biopsy every time “just to be sure” on the front hole, that doesn’t mean I want to have to endure it from the back as well.

We know it was my husband that passed this virus to me because he’s been my only partner, so you can understand my concern. Is it possible for me to have similar problems anally, or does this virus only pertain to irritating the vaginal area? I don’t relish the idea of having to explain to my doctor why I may need an anal probe. I’ve researched everywhere I could find on the net and have not been able to find an answer. Please help!

–No Samples Please

There are more than one hundred types of the human papillomavirus (HPV), and more than thirty different strains affect the genitals, including the ass. HPV is a virus most closely associated with genital or anal warts, although not all forms of HPV cause warts. Many of the strains are potentially cancerous including several that have been directly linked to anal and cervical cancers. It is estimated that as many as one in ten people in the United States has HPV. The development of HPV and precancerous cells is much more common in the vagina because the cervix provides an excellent breeding ground for such cells.

There’s no cervix-equivalent area of the rectum, so it’s much more rare to have pre-cancerous cells there, although you can absolutely spread the virus there. Since just your husband’s fingers have been in your ass (and not his cock), you are only at risk if he fucked your pussy first, then went directly to your ass. If he did, it’s important for you to be thoroughly checked. If you continue anal play, I’d recommend he use a glove for his hand and a condom if he’s going to fuck you with his cock. If you begin having anal intercourse (especially without a condom), as embarrassing as it may feel, you must be honest with your gynecologist, so she has all the facts and can test and treat you accordingly.

My girlfriend saw some ass to mouth scene (ATM) in a porn movie and went crazy for it. Now she wants to do it. I am afraid that it might be unsafe for one or both of us. We’ve only been dating a short time and I have the feeling that the reason why she likes anal sex so much is that she actually likes shit. I also think she would like to felch herself since she often plays with the liquid spilling out of her anus and licks her fingers. I’m not sure I want to kiss her after she does it. Should I be concerned?

–Curious But Scared

First let me say that nearly every activity you describe in your letter, including anal penetration without a condom — which isn’t specifically stated but implied since you’re coming in her ass — puts both of you at risk for HIV, hepatitis, herpes, gonorrhea, syphilis, chlamydia, and other sexually-transmitted diseases. You should both get tested or you should be using a condom and not swapping bodily fluids.

That said, let’s begin with your girlfriend’s ass to mouth fantasy. You’re smart to be concerned about the safety, since there are health concerns with going directly from someone’s ass to their mouth. There is bacteria and fecal matter in her ass that really shouldn’t go other places. The best way to do ATM safely is to pull your dick out of her ass, wipe it with a baby wipe, then stick it in her mouth.

It sounds like your girlfriend is into anal sex, and likes “nasty” stuff like anal creampies, playing with the cum in her ass, and even eating it. I wouldn’t jump to the conclusion that this means she likes shit. It sounds to me like she enjoys all things anal, and there’s a big different between that and being into scat (shit play). You said you don’t want to kiss her after she’s been shoving her ass-and-cum soaked fingers in her mouth. It sounds like maybe she’s also into a couple other butt fetishes: felching and snowballing. Felching is where a guy comes in someone’s ass, then sucks his come out of said ass. Snowballing is when the person who did the felching then “swaps” the cum with their partner through kissing and/or spitting. Safety-wise, both are risky for both partners: if she swallows your come, she can catch an STD from you, and if you get bacteria or fecal matter from her ass in your mouth, you can get an STD from her.

Beyond the safety issues, it seems that you may not enjoy the same things that she does, and that is an equally important issue. I encourage you to talk to her about your health concerns as well as your desires to see if there is some middle ground that the two of you can explore which you’ll both enjoy.

My fiancé and I have always wanted to try anal sex, so we bought your video and we got a beginner’s anal kit. I was wondering though, is it safe for a man to come in your ass? And if he does, do you have to have an enema to clean it out afterwards?

–New to Anal

If a man comes inside your ass without a condom, as the recipient of the come, you are at risk of contracting HIV, hepatitis, and other sexually-transmitted diseases (if your partner has any of these, of course). If you and your fiancé have tested negative sexually-transmitted diseases and are monogamous, then it’s safe for him to come in your butt. What goes in must come out, though, as our butts have a natural flushing-out process. So, you may have a runny bowel movement afterward, but there’s no need to have an enema post-buttfucking.

My husband and I both already have genital herpes and were told not to bother with condoms now. He has recently become enamored with anal sex, but, I want to know, can he spread the herpes virus there? Can you catch herpes when you already have it?

–Submissive to my Dominant

Once you have the herpes virus, you have the antibodies in your system, cannot be re-infected. As I’m sure you know, there is no cure for genital herpes. Many people take medication to treat outbreaks or prevent them. Genital herpes outbreaks can occur anywhere in the genital area, including in and around the anus; however, you won’t get a localized outbreak on your ass just from having anal sex. Two good resources for more information are the website HerpesOnline and The National Herpes Hotline (919-361-8488).

I’d like to thank you for all the advice that you have been offering people, both amateur and pro, who are anal lovers. Your advice has allowed my girlfriend and I to have a wonderful anal sex life. My girlfriend of two and a half years and I have been tested negative for all STDs and are 100% monogamous. This and her taking birth control pills has allowed us to feel comfortable enough to have vaginal and anal sex without the use of condoms. We have never had any problems until recently when I have experienced swollen and somewhat painful lymph nodes around the genital area after having anal sex. Is there anything, concerning anal sex, that could have caused this other than an STD which I am sure that we both don’t have?

–Swollen Lymph Nodes

Lymph nodes are a part of the immune system and they protect the body from “foreign” invaders like bacteria, viruses, cancer, injury, or other harmful substances. Lymph node swelling may or may not cause pain. Swollen lymph nodes around the genitals can be a symptom of a variety of STDs including early HIV infection, herpes, syphillis, pelvic inflammatory disease (PID) and others; since you’ve been tested and are monogamous, you can probably rule them out. But your swollen lymph nodes can also be indicative of a bunch of other conditions, including a hernia, a viral infection, an allergic reaction, a malignancy, or trauma to the groin area — none of which are related to anal sex. My advice to you is to see a doctor and get checked out.
