Haha!!! I was 17 when I first tried with my high school girlfriend. She was sealed shut to the point it was like bouncing my cock off a brick wall. The first attempt was a failure and my ego was bruised!!! We 'broke up' afterwards but hung out all the time together.She climbed on top. It slid into her wet pussy and voila, I was no longer a virgin. (As an aside, though she claimed to be a virgin, pretty much every woman I ever told this story to laughed and said, "she was not virgin". No virgin climbs on top and it just slides in. (And having had a couple of virgins later on, I can a test that it is really hard to break through the hymen with just your cock. REALLY difficult. But again, I digress.))
School ended and I had a Summer job working afternoons. She was at home alone and asked that I come over before I went. I said if I did we'd have to do it... I went over,, we had lots of time and we did it. I was fucking magic. She jumped off early as she was overwhelmed with the experience, but super happy... My dick tingled for a solid day. We were each others' first. I was addicted! (and I think she was too).
I'd say I had a great first experience! She'll always be special to me.
As BF and GF we had immature issues as we were young. We had sex more times in our few years together than I've had with my wife over our entire 15 years being together (dating + marriage). Time past and we split for good... Years later in our young 20's, we did hook-up again and had an electric time. We had a spark together, but probably not a healthy one. We went our separate ways.
This was always my panic! After that first time, my GF was 'late' by weeks upon weeks. I thought I was fucked and going to be a father at 18 (just like my Dad)! What stress! Anyways, that came and went. We still fucked like rabbits; never with a rubber; I learned to control myself and blast it all over her stomach or tits. I'd worry constantly, but I never stopped BB'ing her...Again, the terror of getting her preggers took over and I stopped it before I came
