Okay, I'll share, too. This was now many years ago, so some of it will definitely seem foreign to you all.
I've known I was bi for a while, but I had remained celibate through much of my 20s. Finally at 26 I decided "fuck it, let's do something with someone and just get the anxiety out of the way."
But who? And how? A few times I had browsed the men4men section on Craiglist, and I knew there were always guys looking to fool around. I decided not to jack off for about 1 week or more so that I was horny enough to make dumb decisions and actually make a move. I created a new email account and took some photos, and put a post out there. After a few false starts, a nice guy of the same ethnicity, a fellow grad student, and with a huge member reached out and we decided we'd meet up. He was also bi, and also inexperienced, so yeah let's stumble through this shit together.
We meet at a movie theater so we could end up watching a movie if we didn't feel like more, or we could mess around a little in the dark and see how things went. I had to look up the ending of the movie later because I couldn't really remember what happened, and we didn't stay until the end. Pretty quickly we started touching hands, and pretty quickly I got really really hard. So did he from what I could feel. We made out a little, and then decided to head back to my place, each in our own cars.
I came the first time right away while we were grinding against each other on the couch, but I don't think either of us realized it. We ended up fooling around all night. Just hands and mouths. He did rim me for a while which was fun. We 69'd, cuddled, kissed, chatted, frotted. Really just exploring our bodies and how they react to sensations and how our penises work -- his was uncut and I'm circumcised so we were both fascinated. I remember his had its own smell and taste so different from my own, and that was really fun. For an inexperienced guy he was also a surprisingly good cocksucker. After hours and hours, he didn't want me to cum in his hands but I was too close and let it go. He cum while jacking off with me standing behind him, biting his neck. He was a really big shooter, it was kind of fun to play with it all afterwards.
I know he really wanted to meet up more, but that was enough of that for me. It was like a seal was broken though, and I became a real sexual being. I ended up hooking up with a woman I met at a party just a few weeks later, I think because I felt confident that I can actually do that kind of stuff. She even became like a fwb for a little while. That's a story for another day, though.
