Now, would you really like a woman with a very sharp razor trying to give you a close shave around your "manly parts?" I hope she wouldn't let the razor slip or else you could get circumcised or castrated. If they are going to do this you had better treat them right beforehand.
I used to work with a man about 30 years ago that had a Phillipino wife (cute little thing!) and she'd bathe him and shave his beard...guys didn't shave "down there" back then. He treated her worse than a slave, but I guess that is how she expected to be treated...We always told him that he was lucky that she didn't slit his f*****g throat and he'd say that was why he kept her away from American girls.

You can get waxing done where the ladies do.
