When I was 13 a friend of my stepdad asked me to take my clothes off so he could watch me masterbate, so I did. He watched for a few minutes, then told me to lay down on my bed and sucked my dick. It was so damn hot!
I'm just the oppisite I guess. I never get hard in the gym locker room. I'm usually soft and sometimes as small as it can get. But I still love it. I haven't had an erection in the shower/locker room since I think 7th grade(13).
My first time with a man, or anyone, I was 13. He was a friend of my step-dad, about mid-40's. One morning before he had seen me and a friend my same age come into the kitchen in our underwear. Guess that turned him on. That was about a week earlier. He came over when my parents were still at work and asked if we could go in my bedroom, asked if I could strip naked and jerkoff in front of him. While I was masturbating, he asked if me Andy ever did anything. I told him when he spends the night we sleep naked together and either jerkoff, or jerk each other off. That REALLY turned him on so he came over and sucked my dick. It was so hot and amazing!
