I can't cum during sex

Ok I have orgasmed and even squirted during sex at the age of 16 that's a lie girls can cum before they reach the age of 20

I have the same problem, I'm 21 considerably more attractive than usual (not being cocky just how it is) no girl has ever made me nut despite going at it for literal hours, the girls always cum multiple times and I always hear how great I am but they can never make me come, idk what it is I can cum when I jack off and I do it 2-3 times a day I've tried abstaining for periods of time before sex and it doesn't make a difference, I don't know what to do because like another guest on this thread I know I'm a sex addict but I had a bit of a rough upbringing and I don't trust anyone enough to talk openly about my varying issues, I hope you have found a solution to your issue unfortunately I can't add any advice just solidarity
