Orgasm?

Mia

Hi there, I’m 17 yo, and just have a question about orgasms n stuff. I’m not a virgin and first masturbated when I was like 13, but I don’t know if I’ve ever orgasmed?? I usually masturbate until i get like a big rush and tingly feeling and that’s what I kind of assume is the orgasm, but I’ve never had any like, ‘cum’ or any liquids come out at all? Is this an orgasm? If yes, why don’t I produce any cum?
