During high school, I had a bunch of sexual interactions with several guys. I'll tell you about the one I did the most with, because the most interesting stories were with him (we'll call him 'John'). John arrived a few years into high school, and we became friends quickly as we were both pretty withdrawn guys. At that time I was just starting the become aware of my sexuality, so when we started talking about masturbation quite often my ears pricked up. We'd discuss how long it took to cum, what kinds of porn we were into, how long our dicks were, and so on.
