When I was in my 20s, I became friends with a guy from work who wore boxers. This was back when all young guys (including me) wore briefs. I couldn't help notice that the outline of his penis often showed through his pants or shorts. I asked him if it ever embarrasses him that his dick shows, and he replied "No! that he doesn't like anything tight in his crotch." I bought a pair of boxers to try them for myself. Having always worn briefs and never freeballed, the sensation of having my dick and balls unsupported gave me an instant boner. I would lift my dick up to the 12:00 position and it slid down to the right when I walked and got rock hard. I told my friend that I bought boxers, and he cheered me on to wear them. We started hooking up. I found out that my friend was an exhibitionist, and he enjoyed it when we would go shopping or out in public with both of us sporting an obvious VPL.
I noticed that quite a few guys at college were starting to wear boxers, and you could see a hint of their boxers above the waistband of their shorts or hanging out the bottom of their shorts. The best part was that I could frequently spot their dick outline, and I chuckled to myself that most of them are hiding in plain sight and clueless as to what they are showing off on campus. I saw quite a few semis and a few boners as young guys enjoyed feeling their dicks swinging as the walked from class to class.
As time went by, boxers became my default underwear as I began to dislike snug undies and embraced the loose, casual fit. It always puts a smile on my face when I see a guy sporting his VPL.
