Orgasm Explained?

Dawn

So... I honestly dont fully know what an orgasm actually feels like... Aside form what do with my current SO, my only other experience was being raped and abused in the past. Ive always gauged wether i came or not by how tired i was after but like... My SO really enjoys asking me if i am or not or me saying it when i am...

He tried to explain it but... Honestlt didnt do too great of a job so like ?????

Help???
