How do you recognize an orgasm?

So, I’ve been masturbating for years now, and before watching porn or reading about sex, I thought getting an orgasm was when you felt satisfaction after getting yourself off- and that’s what I feel- except there’s no heavy white discharge afterwards.

I’m sure the amount of discharge depends on the form of masturbation, the person’s anatomy, etc. But I don’t feel a fluid release is what I’m saying. I do feel the satisfaction, but the “cum” isn’t like it’s portrayed in porn or in sex descriptions.
