I'm what you might call heteroflexible. The best description of sex, which I consideran activity and not an attribute, is being intimate with someone, with careful attention to everything about the body. My first trip touching all the bases was with a woman, and I was surprised to learn that some of my men friends had assumed I was gay. I was doing all that could do, both physically and emotionally, with women, but I began to wonder what it would be like and feel like to be with another man. I had fantasies but never acted on them. Years later, after marrying, having a family, and the Internet, I took the leap.
The first guy I was with - a couple decades ago - was in a hotel room where I was staying on a business trip. I met him online and here he was at the door. He was not many years younger than I, good looking, with short brown hair and brown eyes. We looked into each other's eyes and were still for a moment. He just kicked the door closed, said "Hi," put his hands behind my head, pulled me toward him, and kissed me. He had soft lips, and the stubble on his face felt strange. I opened my mouth when I felt his tongue on my lips. My first man kiss. I liked it. He moved his hands to my ass, pulled me against his hips, and ground into me. I said, "It's the first cock I've felt on me." We kept making out as we undressed. He was hairy. I'm smooth. The skin-on-skin felt great as we rubbed our nipples together. We stayed close as we brought our hips and cocks together. I'm cut and he wasn't, which I had secretly wished for. He brought our cocks side by side, and after a few mutual strokes with our hands touching, he brought the heads tip to tip and stretched his skin until it just took the tip of my cock inside. I had never been harder.
