Cant cum while having sex without masturbating while it

Dont know how to explain this.
I have masturbated myself since I was 12/13 (im 20) and had sex since 8 months ago.
I know very well how to please myself but there's something wrong while having sex. I just cant cum if me or my boy doesnt masturbate...

me while having sex, that was fine before, but now I need more, I wanna cum by just feeling him inside of me, I've tried and I have felt it sooo close but I NEVER cum. I mean, I really enjoy having sex and really have pleasure with it but I just cant cum with only that! It's so frustrating to feel like you're on fire, 'bout to explode and you just dont!
Please, I need lot ot tips so I can cum with my boy without touching myself (and no other kind of stuff, but natural things)

ok get him and energy drink and hold on my girlfriend had the same problem but be prepared she couldn't walk right for a few days after

ohh ither that or read up on geting fuly aroused that helps I thing I really dont know ahahahahahahahaha ok yeah or ill fun thing you a link try that

wait,,, what? im talking to firecircle... I dont understand what you said

Well, you might have to tell him how you do and have him try to mimic the feelings you have when you masturbate. If that doesn't work maybe he's finishing too fast.

Basically, you have to talk to your partner about this. It's gotta be an equal effort

imm so lost wheres the whiskey

I dont think he's finishing too fast. We can play almost for an hour and with all of his patience he can cum at least 30min later. We do talk, we do that a lot so it's not a communication problem or whatever. I just dont know what's missing, I feel it coming and then... it's gone!
