Wow ! Haven't you ever been in the military? Haven't you ever been in boarding school and later University dorms?
.........This is normal behavior. Relax. And, yes gays go to "music bars" and straights go to gay bars.
........You were complimented.
What if he would have said, "What a stupid little dick, why are you peeing in public, you little guys should use the stalls, you little dicked guys should hide.

Then how would you feel.
Humiliated.
Rejoice, you got complimented by a big dude, he was probably just trying to make you feel good; and, you responded COMPETITIVELY by saying it gets even bigger when its hard
In fact, since he was taller, you could have easily looked over and given him a nice compliment, too. Like, "Hey, you've got a nice one. too"
I think the kiwis, the guys in NZ are a lot LESS uptight than back in London, and particularly the small towns in England. I love the Kiwi s, love the Aussies too.
