Back in high school I lusted after the boys who I saw wearing briefs when we changed in the locker room before gym or before weight lifting. Still to this day I find briefs on a guy more sexually appealing than any other style of underwear. What kind of men's underwear do you find most sexually appealing on other men? What does your partner (guy or girl) find more sexually appealing?

I'll say I've NEVER understood the appeal of boxers!

So that leaves everthing else as VERY sexually appealing to me! I want things to follow the body's natural curves -- no muu muus please!

I don't think boxers are the most sexy underwear a man can put on but they have their charms. The joy of seeing up the leg holes, the unbuttoned fly spilling open, the loose hang of the boys. All make boxers great for lounging and completely useless for wearing under clothes.

I'd have to say either some form-fitting trunks or low-rise briefs are the most attacting to me...especially like Unico or c-in-2...mmmmm

I love to see a guy in a thong, especially if he has a cute, smooth little butt. It makes me want to fuck him.

Looove seeing guys in Jocks, any kind of straps are just soo hot. I really prefer the athletic ones ( BIKE, GoSoftwear ) rather then the casual ones like Baskit and C-IN2 'cause I can just imagine them working out, stretching, and and being used as they should. I feel sexy and have almost a constant erection when wearing both either my Baskit OR my bike under my clothes while I'm working anyway, though, so..
