Whenever I slow-danced with a girl when I was a teenager, I wondered if they could feel my bulge and even my erection!
One of my earliest sexual experiences with a girl was when I was about 12-13 years old, and we secretly met in the basement of our synagogue for make-out sessions. When we were making-out, we both were fully clothed -- she was wearing a dress, and I had trousers on. We would hug tightly, kiss passionately, and I would grind my erect penis up-and-down against her pubic mound on the outside of her dress. I could feel my erection rubbing against her pubic mound until I orgasmed! My underpants would be a sticky, wet mess afterwards!
A few years later, I was dating a girl, with whom I eventually learned much more about sex. Early in our relationship we would be making out in the front seat of my car. I remember we both wore corduroy trousers back then -- and I have come to associate the feel of corduroy with those sexual experiences.
We would be rubbing our genitals together thru our corduroy trousers. She would become so wet, I could feel it thru her trousers, and quite often I would orgasm inside my corduroy trousers. I produced so much cum back then, that quite often she could feel my wetness thru my trosuers.
Eventually, we graduated to having full-blown sex, which included unclothed oral sex, mutual masturbation, and eventually intercourse itself. She was the wettest female I have ever had sex with, and was the source of my pee fetish!
