Well, an a good deal of Americans, myself included, are pretty ignorant when it comes to uncut dicks. Sure, I have had friends that are uncut but I am clueless about them and I have a dick! I imagine that a lot of American women have no experience other than anecdotal from other women. Likewise, a good deal of guys are clueless too, except for myths they may have heard. So with all that, it falls in the right spot for the brunt of a joke or two. Even though I am ignorant on foreskins, I have been considering foreskin restoration for a while now. The only thing that is holding me back is that I don't know if I will like it or not. That may sound weird, but I have kind of gotten used to my dick the way it is. lol. I just don't know if it is something I would like better than what I have now.
Sorry for the sidetrack... I agree, though. Just imagine a couple of guys in a movie making jokes about running out of the bedroom because of labia. lol
