When I was fifteen I met another boy who had come to visit his aunt and stay with her for a week. He was my age and really nice and we sort of hit it off. I still don't know if he was really gay or not, but he was very persuasive. Somehow we started enjoying the fun of being romantic as boys, which was something that I had never done before and thought that I would probably never do.
After just a couple of days of our being romantically playful, I let him butt fuck me. This was something which he had obviously done with other boys, and I never had. I still to this day don't know how I worked up the nerve to actually do that, but when we did it was so cool enjoying that with another boy. It was great feeling him being male with me like that, and having his stiff penis in my butt, and to have him ejaculate his sperm in me. That week I let him fuck me four times and it was absolutely the most amazing experience.
After he left and went home, we wrote to each other for about a year. Then our corresdspondence fell off and of course I never saw him again. To this day I still think back on my brief love affair with another boy and I am glad that I had it.
