So one of my flexes is that actually I had a great first kiss experience. I was 15, it was with my girlfriend at the time. We had been dating on and off for a few months (this was both our first like serious relationship that counted so it was pretty messy in soooo many ways). We had been best friends for a long time before dating and we always had feelings for each other.
We were in my house playing Dictator on my iPad, sitting on a bean bag in my room. We were cuddling and the tension was over the roof, and after holding the most intense stare ever I ask "what?" (and I knew what was happening but I wanted to play dumb so that she would say it and then I would not have to start it because I was nervous and we had never kissed and thought she might reject me?) anyway and she went "god, I hope I don't regret this" (which like looking back no wonder I was afraid of getting rejected and like damn bitch but also we were teens and she was very nervous too). So she KISSED ME and everything inside me exploded. We proceeded to make out for like a full 40 minutes with some breaks and like got hands under shirts and also this was the first time I ever touched a boob and it was MINDBLOWING and AWESOME (i love boobs).
The breaks we took in between were also pretty sweet. Our relationship up to this point and also after was full of hiding because neither of us wanted our families to know we were together so we were always looking to get intimate in positions were breaking apart at a moment's notice would give us plausible deniability (I still was a cishet man so it wasn't a closet thing back then, but neither of us was ever very close to our families that way). We would play a couple of rounds of Dictator and then make out in the ad breaks. Also my dog was around and wanted to play and was SUCH a bother. In the end the secrecy wasn't effective because the bean bag was right in front of my door (which I was not allowed to close) and we noticed at some point my mom was passing my room on the way out of a room we never saw her walk into in the first place...? So she definitely saw us, we just don't know at what part (hopefully not when we were getting handsy LOL).
We dated for a couple of months more, broke up because I left on a semester abroad, got back together after two years and had a much better, healthier, steady relationship for that time. We don't speak anymore (but that's a story for ANOTHER day) but last we spoke about this we both remember this kiss very fondly.
