I was going out with a girl who didn’t want to tell her family she was gay, so they all thought I was just a good friend. We’d been going out for a while when I went to a party that her older brother was also at. He was quite a few years older than me. He got pretty drunk and halfway through the night he came up behind me, put his arms around me and started kissing my neck. He said he’d wanted to jump me for ages and asked if I wanted to find somewhere more private with him. I’d never been with a guy before, but I was curious. He was really hot and I was rather drunk too, so I ended up agreeing. We didn’t have sex, but only because neither of us had any protection with us. I told him not to say anything to his sister because I didn’t want her to be upset with me for getting it on with her brother. But after a couple of weeks I still couldn’t stop looking at him and wanting to have sex with him. I ended up asking him to come around my house one night when I knew my girlfriend was busy, and we had sex for hours. It was fantastic. He showed me all sorts of things. After that he started coming around at least once a fortnight when I knew my girlfriend would be busy. I was loving learning sex with a guy, but I felt really bad that I was cheating on my girlfriend. After a few months I realised that the novelty of sex with him had worn off, and I wasn’t all that interested anymore, so I told him I didn’t want to see him anymore. That was a few years ago, I’m still with my girlfriend but I’ve never told her. I love her, but I’m really glad I found out what sex with a guy could be like, her brother taught me a lot.
