This might be a stupid question🙈

Sooo i’m a little confused about orgasm/cumming. I orgasm sometimes during sex but mostly with a vibrator.. but i’m confused if i really have came or not ... i definitely feel something but the only way i can describe my ‘orgasm’ is like a firework that doesn’t go off, i can feel myself build up but it turns to nothing. I also have never creamed or squirted but i’m not sure how common that actually is. Can anyone shed some light on this, have i actually? Will i ever cream or squirt? TIA xxx
