Can anal sex get a girl pregnant?

No, but... if you are so young you don't know this, you have no business having sex.

Ummmm... no. Not trying to be mean but if you don't know the mechanics of pregnancy, then you probably shouldn't be sexually active. If you are not ready to encounter pregnancy... take preventive measures for every kind of sex.

No but if he inserts in the vagina after anal sex(which is very risky for infection) and there is sperm on his penis(it only takes one) then you can get pregnant.

Umm I'm 18 and I was just curious cause I was not sure but thank you... and yes, I am a virgin that's why I was wondering.

No, but don't force it on a young girl.

My girlfriend is 18 as well. She's a virgin too and her whole life she's been pretty prude... I like that a lot though now she just wants to have sexual relations.

The answer is simply this... not directly, but the proximity of the vagina to the rectum and even a tiny bit of seminal leakage combined with the movement of her underwear could potientially deposit it at the vaginal opening... from there it is possible to reach the uterus and cause a pregnancy, not likely, but possible. And you should deal with possibilities rather than statictical odds against.

Because it does happen.

You can't be 18 and not know this... virgin or not! Ok kid... if you have to ask such questions... you are NOT ready for sex!!
