A funny pool (I think) How old are you when you undestood ballbusting is funny/exciting ?

I am personally curious and I want to undestand when people, for the first time ever thought "I will be happy if a girl kick me in the balls" or for a girl "I will be happy if I kick a boy in the balls"

Let me know what you think about it, any thought or funny story
