How do i know if i had an orgasm?

Okay so, usually when i masturbate nothing ever happens but yesterday i was talking to my boyfriend about sex ( we were on the internet) and all of a sudden i felt this tingling feeling down there, and i went to the bathroom and i was "wet" but ive gotten this feeling before and i never get it when i masturbate and if it was an orgasm it really didnt seem as amazing as people make it sound like?
