@goodgolly - agreed. It also seems to be the same at nudist places - seems guys willing to get naked around others tend to be better endowed on average. That's not to say there aren't guys on the smaller end there, too. Of course, lots of people at nudist places are also in the lifestyle, so we're talking about some of the same type folks.
Alot of this is just semantics, though. To some people the "well-endowed" guys might be smaller that what they'd call "hung" and even less than what they might call "monster." In all cases, I'd expect they mean a guy significantly bigger than what they consider average.
