As a mother of three sons I agree with you Perna. But then again, I taught them all to ask themselves "is this the person that I want to be the mother/father of my children?" I certainly know that sex is not only for procreation; I have four children, each and every one of them was concieved while I was on birth control. The twins were after my husband had a vasectomy.
It makes me very angry that men and women go around having kids and not pay attention to the person they're having kids with. That they're actually surprised when someone ends up pregnant.
