What does an orgasum feel like?

...So I don't know if I've ever orgasumed before, I've never had sexual Intercourse before but when I masturbate after a few minutes of rubbing the clitoris I get a strong feeling that starts in the vagina then goes through out my whole body and I get hot and my body feelings tingly like my whole body went to sleep very unexplainable and this lasts for maybe a few seconds then its gone and the clit is a little swollen, Is this one way of an orgasum? Or something else
