I recently had a visit from a fellow jockstrap enthousiast. I kept my jock on, while made out and did his deed.
Its the best if you were required to wear a jockstrap in the early 90's
when I was stationed in Japan, the gym loaned out socks, shoes, jock, shorts and t shirts. I had a card with my name on it, and the sizes that I needed. I used it ever day I could. It was awesome to get a different jock ever day.
