It seemed to me and his behaviour looks like he wad sexually assaulted,but his penis reacted and this is why i can think about that like he wad s.assaulted.i friends friend is a therapis said that is possible that someone could be in kind of shock when he was sex.suprised by someone he knew and didnt plan it.I try to understand this situation but i cant understand why he didnt stop the intercourseafter first shock passed,he can explain this:(its frustrat,and sometimes i want to kick ass this ow altgough it not my style
