text: my boyfriend loves to watch me pee in the bath tub before we have sex, and it really turns him on to watch? why does this turn him on? i think its weird! any other girls been asked to do this by their boyfriends? it's not some think i would do, but if that's what he likes and your happy to do it then that's up to you. i'm pretty lucky because my partner and i are into the same things in the bedroom dept.
