thats a really odd comment to be honest, boxer shorts are certainly not universal, i dont wear them, dont know many ppl that wear them at all. its culturally specific to certain countries.
and a Slip? that is female underwear, lingerie, did you mean a towel?
meanwhile, those are briefs. but obviously, as you said elsewhere, "sorry my english is bad....".
butt seriously,. boxers are entirely redundant, they do nothing that you pants dont already do.
men wearing clothing purely for vanity reasons = gay as fuck, seeing as you keep wanting to go there.
im also not the one posting pictures of men in underwear..
