The university campus is the best place to show your dick through your pants or shorts. When I was a student at SDSU, I was extremely fit and looked great in whatever I wore. Briefs were my default underwear. Kept everything in its place. Many guys wore boxers, especially the younger ones. Loved seeing them wear boxers and gym shorts - you could see everything. I tried boxers at home, but would always get rock hard because I wasn't used to no support. My hard cock hanging in boxers was painfully obvious, so I never wore them outside of the house.
As time went by, I started to notice so many hanging dicks on campus, I couldn't believe it. No doubt that some of these guys with swinging dicks were freeballers, but I never thought of that back then. I assumed that it was a fad that most guys were switching from briefs to boxers because they weren't shy about showing their underwear. In a weird way, it turned me on and I was dying to go to school with my cock loose. Months later, I got brave enough and started to occasionally wear boxers to class. I'd play a game with myself to see if I could make it from one class to the next without getting hard. It never worked. I'd feel the head of my dick swinging with each step. It would rub lightly against my clothes and I'd end up with at least a semi whenever I walked. I could get a fairly big semi without it looking obscene, but if it started to get all the way hard, I'd have to stop or it would hurt. I'd always get fully hard with Levis jeans and boxers - it was just a matter of how many steps before it engorged. My sunglasses prevented the gawkers from making eye contact with me, yet I would see them look down, look up, and then look down again. I never let on that I saw them looking. It was cool.
Then I quit wearing boxers and went back to briefs for about 6 years after I graduated. 2 years ago, I got back into boxers. Now that I'm used to hanging loose, I only wear boxers and rarely get hard in public. It feels excellent to not be restrained in briefs, especially in mesh gym shorts or track pants. Sure, I'll get semis every now and then that show the outline, yet most of my clothes are loose enough that it doesn't case a scene.
