My opening disclaimer: I don't usually wear men's lingerie. I feel like I look silly (though let's be honest, I'm not wearing this because of what I think I look like). My wife isn't a fan of most of it (she'd rather me in firefighter uniform or in jean, no-sleeve, and a tool belt). But, these were a hit for her.
I'm wear boxer briefs on the norm, so these are already within my comfort zone. My normal ones are the cotton kind that eventually get a little baggy. I also have sports spandex kind, and these are similar in that they have that snug fit and smooth feel. However, these do a better job of accentuating the entire area and looking a bit fancy rather than the sporty kind. They fit great; the sizing seemed spot on.
