I tried talking to guys at my gym, but most seemed to already have their cliques and it was tough work.
I never reveal my man bits, always covering up with a towel before and after showering.
One day, though, I popped into the sauna (with towel around waist) about 5 guys were in there, all naked.
I felt a little uncomfortable in my towel so went for another shower and returned - without the towel.
While not sporting a raging hard-on, my pecker was swollen a little more than usual from the shower and the exhibitionist streak I have.
Glancing down, I could see that he looked pretty good.
Now all the guys talk with me (this was a side-effect - not my intention) and after a workout, I'm even asked occasionally if I'm going for a sauna.
So my advice would be "Give 'em a peek...You'll be flavour of the week" LOL.
