Well I'm not gonna laugh so to be fair, I'll answer you when I was still 15. I have kissed roundabout countless girls.
I am 26 years old. I've not any counting that how many girls i've kissed. I have lot of girl friends school time, collage time, personal. Kiss is not big issue. It is common today.
I am 25 years old, I wanted to kiss her as much as possible and it's all there is no coercion but love each other
