I didn't learn or enjoy anything about sex as a teenager with other boys, but I had a couple of friends who were brothers and we'd hang out and do stuff boys do quite often and they had two sisters. But a couple of times we were in their room comparing dicks and getting ourselves hard in front of each other for kicks to see who was the biggest and their little sister walked in on us.,
I did, from the age of eight onward; I never even saw a woman's body that wasn't a two-dimensional airbrushed image in Playboy until I was in late high school. I absolutely loved cock, and continued having sex with guys throughout my life.I've never not been Bisexual.
I admit I did. Early Betamax pirated porn videos, watching with a mate and you sometimes do things when horny that wouldn’t occur you when not. At least that was my explanation, but what started with a kiss went a whole lot further!!
My cousin and I grew up together. As young teens we would look at porn magazines and jerk off together. Eventually a neighbor kid joined us and we began doing it to each other. We just enjoyed how great it felt and it continued for several years.
