...because of his penis? I mean, when you are both in bed or getting undressed and you see his penis and are like, "no... just no"? I mean, I just kind of assumed that once you are in bed with eachother it is going to happen unless there are other problems (break down crying, ED, somebody says something, etc). I ask this not for myself, but because every now and again I see a thread asking if a girl would fuck a guy and they only provide penis pictures. I cant help but ask myself, "why are all these guys flashing their penis to women asking for sex?"
