I'm confused. Can it be orgasm?

Whenever my guy eats me down there, within 3-4 mins I cum and it feels so nice. And when I rub my clit for at least 10-20 mins at a moment it feels too nice and I cum a lot. My legs shake a lil bit. But I don't cum in that speed in which girls squirt in porns. I think I never orgasmed. Is it orgasm? Sorry if you think I'm dumb
