Okay, first gotta say I feel crazy uncomfortable in lingerie sections, but my mom and friends invariably take me into them. I go with boxer briefs, personally, and am undergoing a personal agony currently as I'm living with my folks for the time being and if they saw these in the laundry, they'd kill me. Even women's "boxer briefs" (called boy briefs, usually) don't begin to compare to men's, but I guess I have to grin and bear it.
