I found a site called showyourdick.org. It's quite perverted. A bunch of guys showing off their bits, but some of them are...missing a couple things.

A couple of them don't even have a sack to ever put prosthetic balls in them so they can look like men again. If you read their comments, you'll learn that one can't get erections anymore, gave up on sex and hormone replacement therapy. One has painful erections post surgery, cause there's less skin to jerk off with. And one has his sack, but it kind of shrunk. There are no doubt more of these eunuchs around than I thought
