We talkin' stuff with midgets, Dave? Because I'll see you two Midgets and raise you a Granny.
(My father's Porn Closet... contained horrors.)
I don't think guys often get a chance to discuss the matter of circumcision. I feel it's considered "impolite", or something they're Not Supposed To Talk About. I've actually had friends who didn't know what a circumcision was until they saw porn, or else they weren't but every one they'd ever seen was, and they had never had it explained to them so they thought they had something "wrong" with them. I don't know, it doesn't come up a lot and I'm not entirely sure why.
I couldn't give you statistics, Dave, but I think at one point it was a "standard" procedure that started falling out of favor in the late-70s or so. Like, it's often thought of as a Jewish thing, but my family's Catholic and it's just the universal thing. I think at one point it was an "Everybody's doing it!" kinda thing, but then someone published a theory that it could cause trauma and after that it started getting scaled back. So it's less common than it was, but I'd wager it's probably still a majority. Just a guess though, never took a survey.
