I kissed a girl when I was 9 but it was more than kissing it was snogging, it first happened when we were playing a kind of game, then like 8 more times. Kissing then always felt good, there was no such thing as anything going bad. I had a kind of addiction to that until the girl just started to go weird and move back when I tried to kiss her. I think now that I wasn't in love with her back then, more like addicted to her. I didn't kiss anyone like that for 13 years now, but most of all never kissed a girl because I love her...
To be honest I don't worry about becoming a bad kisser, what I worry about is how will I ever be in a situation where the next step is to kiss each other.
