I was so sad to hear of Jack Morin’s passing. He was a true innovator and the author of two of the most important books on sexuality: Anal Pleasure and Health and The Erotic Mind. When I found out that Morin was dying, I wrote him this letter. I am sharing it here to celebrate his amazing life.

Dear Jack,

There really aren’t enough words to describe just how important your work in the field of sexuality is, but words are all I’ve got, so that’s what I’ll go with. I feel like none of my work could exist without yours. When it comes to anal sex and anal health education, obviously, you wrote the book. But it goes far beyond that: you broke the ground, you blazed the trail, you opened up the discussion, and you boldly put your name on all of it at a time when no one was talking about this taboo subject. By doing so, you made so many things possible. Anal Pleasure and Health has a pivotal place in the history of sexuality and sex education in the last century, and I am forever grateful that you wrote it. I still have my copy of what I think is the first or second edition, the one I read in the early nineties, with its dented baby blue cover and pages all marked up. I was interviewed last month for a full page article in Glamour magazine about anal sex, and that’s just one example of the tremendous cultural shift that’s happened in the dialogue about anal pleasure. You made that happen, basically. It all comes back to you. You made it possible for my book—and countless other books, articles, websites, videos, and workshops that discuss anal sex—to exist.

You’ve left a legacy of shame-free, sex-positive, holistic, pioneering work on anal pleasure. It inspired me to write my book. And I know it has inspired thousands and thousands of people to explore anal pleasure in their lives. And that’s just one of so many things you’ve done in your career. You are a leader and a light in the field of sex education. From the bottom of my heart, I want to express my gratitude, my respect, and my awe for everything you’ve done to make this world a better place. I promise to honor you by taking the torch you lit and setting the motherfucking world on fire. I’ll do my best, anyway.

I know the ass is sensitive, but how many nerve endings are there in the ass? Is it the same in guys and girls? And are the “good feeling nerves” located in the sphincter or the rectum?

–Curious About Anatomy

The anus (the anal opening), the anal canal (the first few inches inside), and the rectum are all sensitive in different ways, which is why anal stimulation and penetration can be so pleasurable. The external and internal sphincter muscles surround the anal opening. These muscles can work together or independently of each other, and these are the muscles we must learn to relax in order to achieve comfortable anal penetration. When we talk about the sphincter and pelvic muscles and how they play a role in anal pleasure, we discuss them less in terms of sensitivity and more in terms of how tone and “in shape” they are and how tense or relaxed they are. The anus and the outer part of the anal canal are made of the same sensitive soft tissue and this tissue contains the most concentration of nerve endings of all our anal anatomy. In general, this tissue tends to be more sensitive to touch and vibration. The inner part of the anal canal and the rectum are mucous membrane and have a lot less nerve endings; however this tissue is much more sensitive to pressure (like from penetration).

Men and women have nearly identical anorectal anatomy except for one important difference: men have a prostate gland, which can be stimulated directly via anal penetration. The prostate gland surrounds part of a man’s urethra; it’s behind the pubic bone, below the bladder and above the base of the penis. A mass of muscle, glands, and connective tissue, the prostate is about the size and shape of a walnut; it produces ejaculatory fluid that combines with sperm and fluid from the seminal vesicles to create male ejaculate. Men can experience direct prostate stimulation when they are anally penetrated. It can be found by sliding a finger (or toy) about one to two inches inside a man’s ass and aiming toward the front of his body.

While women don’t have a prostate, but we do have a G-spot and can experience indirect G-spot stimulation through anal penetration. The G-spot is the urethral sponge which sits around the urethra; to find it, slip a finger inside her vagina an inch to an inch and a half and toward the front of her body. The G-spot can be stimulated through the front wall of the vagina or indirectly though anal sex.
