Oh, you see, that’s not the same thing. Most gay men are absolutely fucking terrified of vaginas, for example. A total mystery that, for most of us, we have only ever encountered in a biology class. (On the other hand, we probably know more about them from that biology class and our lady friends than most unmarried straight men). However, even as a straight guy, you could admit that dicks are fun to play with, even if it’s just your own. ¯_(ツ)_/¯
Ya see, as best, as I can figure, the boob thing for gay guys is that, it’s a novelty because we don’t have them (usually), they’re actually kind of neat and fun, and if you push them together, they look like a butt, which is something we actually do like.
