I'm a str/bi/cur guy. My wife, family and friends don't know and I plan on keeping it that way.
Years ago, I got turned on by pictures of guys in small briefs. So, I made a transition from boxers to briefs. I really like the ultra low-rise cut and that's what I wear to the gym.
So, I'm curious. Is that a signal of my sexual flexibility? Would any of the gay members of this site look at a guy in low-rise briefs and say, "He's one of us."
Finally, what underwear do you wear and why?
