So my issue is that I can only cum from handjobs, I'm sure its from years of masterbation and thats what I'm used to. When I have sex it feels good, oral is much better and I show my girl how worked up I am by groaning and what now. But I asked her if it was alright if we could have sex or fool around and I could give her orgasm but hold back myself. I don't get blue balls and I like feeling horny throughought the day, expecially when I'm around her. I'd rather hold it in and just explode at the end of the day . If I want to cum I'll bring myself off or jerk it while I'm half in her mouth, feels great BTW.

She gets frustrated when we have sex and I hold back and don't want to cum. The girl before got so frustrated that she couldn't make me cum through sex it ended the relationship. I understand where they are coming from but I need to reframe things in a woman's mind to make it okay for me to hold back. Just because I don't cum doesn't mean it didn't feel great. Cuming early in the day makes me more tired, less enthusiastic, makes my gym workouts harder, etc bla bla bla. The last thing I want is to have the opposite problem of being too sensitive, now I can have sex for as long as I'm interested, which is a long time.

Help with reframing her and all future girls please.
No bs answers no flaming. I'm just going to assume people with stupid responses are forum lurkers and not even trying pickup in the real world.
