Makes me wonder why we send our kids to school. Sure, they can read and write but how do they learn to survive in the real world. The world of becoming sexually active? Why isn't sexuality a subject more important than the above?
Carifairy is right. 27% pregnancy with the pull out method.
Parents need to pull their heads out of the sand. Their kids are going to have sex, like it or not. Do parents really have the courage to teach their children about sex, what makes a baby, what prevents pregnancy? For the most part, NO!!!!!!!!
Teach your children or face the consequences when they get themselves in over their heads. And, remember, babies that come to your children when they just don't quite get the picture are pretty much gonna land in your laps.
The reason urination is a part of the equation is because of the way sperm gets into precum in the first place.
There is no sperm naturally occurring in precum. It gets there from a prior ejaculation. Leftover sperm in and on the penis gets mixed in with precum and can impregnate someone if the man has sex again before he urinates.
Urine clears the leftover sperm from the penis so that the next sexual encounter will have less sperm in the precum.
