Dear beagelgirl,

Pregnancy can happen when ejaculate or pre-ejaculate gets in the vagina or on the vulva. The most likely way to become pregnant is through unprotected vaginal sex.

However, if partners engage in body rubbing with their clothes off, there is a chance that ejaculate or pre-ejaculate may come into contact with the vulva or vagina — which can cause pregnancy, even if partners don't actually have vaginal intercourse.

If partners are concerned about the risk of pregnancy from body rubbing, they may want to consider using condoms or another method of birth control. Condoms also reduce the risk of sexually transmitted infections that can be spread in ejaculate and pre-ejaculate.

If partners have reached the point where they may start having vaginal intercourse, they should talk about what kind of birth control they want to prepare themselves with before they start having intercourse.
