Weird pulse down there

So after I masterbate(by rubbing my clit) I get this weird pulse down there for like 5-10 min. I don't think I orgasmed I mean I get these 5 second moments where I feel super good and my body tingles and twitches a lil but idk what it is I don't think it's an orgasm based on what people say about how theirs is. But yea can someone tell me what this is
