I was discussing this with a friend, and another thread here on SF made me think of it again. Is it common for men and women to have impregnation fantasies? My guy friend said it is. I admit to having a similar fantasy, but it's more of the telling the impregnator that I am with child, not the act of conception itself, that I find erotic. I suppose it comes from the fact that when I got pregnant it was unplanned and there was a lot of stress, anger, confusion, and anxiety when I told my then boyfriend, now husband, about it. I had always thought when I got pregnant I'd be married first and the news would be joyous, but it didn't work out that way. In my fantasy, I tell him I'm pregnant, we are both elated, then have mad, passionate sex.
