I'm of the younger generation and I've got no problem getting nude in front of other men. Well, I don't really have much of a problem getting nude in front of anyone, really. I do find it odd when other people don't get naked showing in a locker room or when they go to great lengths to cover up. I guess it's easy to say this when you've got a big cock, but no one will remember in five years if you're hung like a horse or a button. If you look around a locker room shower with 20 guys in it you'll most likely see a lot of average cocks with a few big ones and a few small ones thrown in. Besides, I've seen a few that look really, really small when flaccid that grow to be pretty impressive. If you're really that worried about it, you can always go with the "I'm a grower, not a shower" line.
