Unless a woman is braindead she won't get pregnant unless she MEANS to. She can always say " But I thought I couldn't get pregnant " or " I only missed one pill, it was an accident " blah, blah, blah...in the mean time she has sex without a condom opening herself up to god only knows how many STD's, or unplanned babies, then all of a sudden she wants monthly checks from Mr. Man himself, who through no fault of his own has to live with WHATEVER choice SHE makes, ie. birth, abortion, adoption.
Yes he made a mistake too by not using a condom, but that in NO WAY is a contract to allow her to decide his parental, or financial fate.Why does she get all the choices?? That is what is not fair.
Lot's of men are going to penetrate as many women as will allow them to. It's a part of life that no body can change and to think otherwise is a fantasy.
