A poorly worded question because I am not sure what I am asking. How often do women purposefully get pregnant or have sex just for the sake of having kids? I know women that were impregnated by people other than their mates. Mostly because they were messing around and got knocked up. Sometimes the mate knew or found out years later. Other times the mate never acted like he ever found out. Sometimes the man could not have kids and they wanted kids. I was offered to impregnate a couple of women as an active sperm donor. It never happened. From what I have seen, I am glad it didn't. None that I was involved with, I have seen paternity suits later. The men went from supposedly anonymous sperm donors to child support paying Daddies. I was also asked if I would impregnate a single friend before she got to old. never happened - she found a husband How often do these sorts of things happen? It seems to me that it must be pretty common, if I have seen so much of it.
