I tried everything because I'm that dude that cant sit still for more than 5 minutes in a movie theater, I'm the Al Bundy type who's always readjusting his crotch, so the only underwear I found that works for me is this Jockey sport model here.... at first I started wearing them just for when I go workout and play sports since they're sport undies that are 80% polyester and 20% spandex, but then I decided to buy a whole bunch for every day use as well and throw all my old ones out, I havent worn anything else now except these for over a year now.... they come in super long length like seen here or a bit shorter, I get the long ones cuz of all the activities I do feels real nice under my shorts
