Cumming or what?

When I’m riding my boyfriend a certain way, I feel the same kind of climax that I do when I’m stimulating my clit. I call it cumming, not that I’m getting excessively wet. I’ve never climaxed any other way. Does it still count as cumming? Is that what an orgasm is, or is it something else? Google can’t help me 🤷‍♀️
