My first time came late. A lot later than it should have.
When I was 12, I was in a boarding school and this boy got me alone and blew me a couple of times. I had no idea about sex, straight or gay. So, when he asked for reciprocation, since he had been playing with it for some time and had pre-cum on it, I asked him, to dry it off. Remember, I had no idea about anything. I probably should have done it myself. I would have sucked his cock, but he got mad instead.
I thought there was something wrong with me. Unfortunately, I mentioned it to my mother, and he was moved to another building. My mother made it sound like the worst thing in the world and, after I returned home, checked every night to see that I was not playing with it.
Over the years, a lot of guys made passes at me, but I was afraid.
Finally a friend, who was gay, noticed how I avoided public showers and other things. One time when I dropped him off at home after work, he invited me in for a beer, and I went in. He had all kinds of gay porno on the table in the living room. I could not take my eyes off of the naked men, some sucking it, others getting fucked, some just naked with a hard-on. I was obviously interested, and he gave me some to take with me.
About two weeks later, I told him that I was interested in trying it. I had bought a dildo in the mean time and was fucking myself with it once or twice a night. I gave him a ride one night, and we went to bed together. When I saw a real live naked man with a hard cock, I moved between his legs, kissed the head of his cock (it was huge), and put the whole thing in my mouth. I sucked him in many different positions until he positioned me where he wanted me, and fucked me.
It was the very best sex I had ever had, and I have not touched a girl since (nor do I want to)!
