When I was very young (about 5) I saw some commercial for AIDS or teen pregnancy and the commercial ended with something like "Make sure you know what your kids are thinking about sex.." And from then on i tried to never thing about sex or pregnant people because I thought if you thought about it you would become pregnant.
