yeah 2xist is a gay oriented brand, they advertise heavily in gay magazines and all, i had a few pairs though i didn't like them, they were comfortable but the fabric was too thin and they didn't hold shape too well particularly around the seat (like grandpa undies after a few hours lol). two other gay oriented underwear brands are ginch gonch and dtjocks. dt briefs personally are the most uncomfortable i've worn because of the binding on the legholes which don't allow for much stretch. it feels like rubberbands around your legs.
im calvin klein high cut briefs all the way but a friend gave me a pair of japanese brand "uniq-glo" boxer briefs, similar to gap in america and they were very good quality with a understated look.
