There's a young dude who just started at one of the gyms I go to whose erect or semi-erect penis is almost always visible through his sweats. He also frequently touches it between sets or bs-ing with his boys on the gym floor, a habit I see a lot among the young working class guys there who come out of a macho culture. I get turned on by this, but know it could be a big draw-back for this guy. I looked up info on-line that claimed that constant erections could be caused by medical conditions. I also know that people in "polite society" are offended by visible erections, and by men unconsciously but frequently touching there penises in public. Should I say something to this kid about this? He's friendly toward me but I don't know him well. I should add that this is in the context of a public university with a mostly working-class population that often doesn't know how their unfamiliarity with middle-class norms work against them. How would others handle this?
