how to know if you had an org?

i know most people say “you’ll know” but i just can’t tell. i normally stimulate myself with either my fingers or my wand massager. so it starts off by just feeling really good, and then it’s like a rising feeling, like reaching the peak of something. and then when i reach the top of whatever, my stomach starts like contracting, i start curling up and moving around and stuff and then after that, i know that i’m done because my clit starts hurting if i keep rubbing or keep the vibration on it. now i’m not sure if that’s necessarily an orgasm because my cooch is just super super wet but nothing white comes out unless it’s not supposed to be white. if this isn’t an orgasm, how do i get one considering my clit hurts after that peak?
