My girlfriend and I just started having anal sex; thanks for your wonderful web site and all your great advice. I was wondering, would a fairly good amount of semen in the rectum do anything bad? Or would you recommend against it?
Lots of people ask about having unprotected anal sex, and if ejaculation in the ass is harmful in any way, and the answer, like those to many questions is: it depends. If you have anal intercourse without a condom, both partners can be at risk of contracting HIV, chlamydia, gonorrhea, syphilis, herpes, genital warts, and hepatitis. The risks increase for your partner if you ejaculate, since semen has a high concentration of HIV and many of the STDs mentioned. If you and your partner tested negative for all these diseases and are monogamous, then having anal sex without a condom and coming in her ass is safe. Since you described your load as “a fairly good amount of semen,” I’ll remind you that what goes in must come out, so the semen may dribble out of her ass (along with all the lube you put in there), but a quick trip to the bathroom should take care of that!
