How many men have seen your wife naked? Were any of them friends of yours? My wife had sex with two guys before we started dating and of course they saw her naked. While we were living together I took her to a nude beach and many guys saw her laying on her back with her legs spread. We also went to a nude beach with my best friend growing up and he saw all of her.
I don't believe that anyone except her doctors have seen her naked since we have been married.
