Yeah, I'd love to do that! The dude is probably 48, and looks great. He has a shaved head, sometimes a beard, sometimes not. Blonde. Hairy chest. Awesome smile. And he has a very nice looking cock and balls. Looks like a show-er. But I think it would grow quite nicely, too.
We have often talked about underwear. He always wears colored briefs, FTL or Hanes. I usually wear colored and patterned briefs as well. We've talked about support the briefs gives us, and how boxers don't quite do it for us. He has commented on my patterned underwear before.
Another guy I used to see there often once said "I see you got the memo that it's white Calvin Klein underwear day" when we were both changing into CK briefs after our showers. That started up an underwear conversation of course.
