Orgasam || Cumming

Ta
What does it feel like? As many different opinions as possible please....cause I don't think I have....
I've honestly had to fake everything for every guy I've had sex with.
My current BF is the only one I truly enjoy having sex with and get turned on and idk I don't even "finish" when I masturbate I just have to stop after a really long time because it becomes too much.
Some people say that when you get really sensitive you have finished but idk.
No matter WHAT I do I can't seem to cum or finish it if I do I don't know it! -_-
