obviously i'm not a doctor but i can tell you from my own experience with my wife. she does not take birth control pills (we don't believe in it). the method we used was either the cycle method or the pull-out method. did this for years and she never got pregnant. and when we actually tried to get pregnant for real she got pregnant on first try. so my point is in our case. there was an almost zero chance of getting some pregnant from precum.
can a women get pregnant from precum (pre ejaculation) and if she doesnt have an orgasim?
