My paramour seems to be preoccupied (to say the least) with the idea of anal sex. We’ve tried before a couple times, none of which ended well. I blame it on my own trust issues and the lack of lube. But it’s been a while and I’m feeling better (and braver) about it all. I recently read something about the possibility of semen finding its way from your anus to your vagina and impregnating you. I need to know if I’m gonna have to consider a contraceptive before allowing my beloved to go-a-spelunking in my magic cave without a raincoat! I’d hate to have to explain to my kid someday that he or she was conceived by mommy and daddy getting freaky in the butt!
–So Not Trying To Have A Butt Baby
First let me say that I am pleased that you’re willing to give anal another try — I promise you that lube will go a long way to making it a lot better! If I only received a question like yours once a year, I’d chalk it up to an ill-informed young person or an Internet jokester. But, believe it or not, I get at least one question about becoming pregnant from anal sex nearly every day. So let me reassure you that you’re not the only one who’s heard this rumor or is concerned about it.
Technically, the scenario you pose is possible, but it’s very, very unlikely and improbable. Semen would have to drip out of your ass and into your pussy and survive the transfer outside the body (sperm cannot live very long when exposed to air). Then, a cock or finger or toy would have to push the semen inside, so it had a shot at getting close to the cervix, through the cervix, into the uterus and fallopian tubes. It’s a long journey and beginning in another place doesn’t help matters for those poor sperm.
If you are seriously concerned but want to go condom-free, I recommend taking a few precautions. Have your partner ejaculate in your butt in a position where gravity is working in your favor, like missionary or spooning. As soon as he pulls out, make sure to have a baby wipe handy to catch any dribble and prevent it from migrating toward your puss. Use another baby wipe and give yourself a full swipe from front to back. That ought to cover you!
