Definitely a nice ego boost. Where else can you go as a straight guy and have someone comment on your dick?
I'm always shocked when someone asks me on here about people making comments in the gym showers, or at a urinal, or other such situation. That's alien to me and something I'd never even thought of until posting here. Would be quite uncomfortable if someone was peeking at my penis over a divider in the bathroom, lol..
If someone enjoys the sight of my dick, excellent. My penis is my favorite subject, but there aren't many outlets you can go to talk about it. Plus, the anonymity is excellent.
