Sorry for my english
I'm a boy, I'm 16 and it's since 12 that I've never started masturbating like everyone else, moving it up and down, but from the beginning it came naturally to me, without even thinking about it, in a few words, lying on a surface and with a lot of pressure crawling the penis between my legs and since I was a child I got used to it, so now at 16 I would like to do it like everyone does, especially for my future relationships, how do I do it? I've already tried to do it up and down whit my hand, but I don't feel any excitement, just a very small sensation, but I don't even know if it's that, and like i fell nothing please help with something, for example if it happened to someone, like they did or something similar
