My first kiss was at 18, with a guy I'd had a crush on since I was 14 (we were never a couple). We'd actually lost touch for about three years but ran into each other randomly and started hanging out occasionally again. We'd gone to see a movie that night and then spent a bit of time just driving around and talking (if I remember correctly there were lots of awkward silences as well, haha), and then he dropped me off at home somewhere around 1.00 am. We were standing outside the back door saying goodnight (again, rather awkwardly

) and he gave me a hug and then leaned in and kissed me. I honestly can't remember if we kissed once or twice... but I do remember that although I was excited about the whole experience in general, the kiss itself just felt kinda... meh. Like lips on lips, or wet slugs or something. It wasn't nearly as exciting as I thought it was going to be, haha. It undoubtedly was
not this guy's first kiss... and I'm certain he'd done far more than kissing with other people.
The next person I kissed was a little over a year later when I was 19, the one and only time my very extroverted and clubbing-obsessed friend dragged me out to go dancing one night. (A crappy experience that I'd rather forget...) I was drunk as hell and I barely remember the kiss (and don't remember the guy at all), but I felt pretty disgusted with myself afterwards.
Didn't kiss anyone again until I was 24... and I'm married to him now, haha.
