Shiiiiiit I've been doing that since 7th grade junior high after swimming in gym. The gym teachers taught us too but man I remember so many kids being terrible at it haha.this guy said:Just bring a towel with you to the shower so that when you get out you don't have to walk around naked. There's also the college dorm room trick of pulling up your underwear while you still have your towel around your waist, so that when you take off the towel you're already clothed. Boom, problem solved!
Of course I did this in college too.
