I've always loved to show my dick. I remember when we were playing in the woods behind my house with my friends, we had this game where we were superheroes who had to capture a bad guy. Once in captivity, the bad guy had to keep his shorts down, his penis in full view. It gave me a hardon every time. No need to tell you that I managed to be the bad guy most of the time. I didn't knew it yet, but it was going to become a first step towards more discoveries and fun with some of these friends...
