I've only had this one partner and I have no inhibitions, I'm very comfortable and open-minded. When I'm with him, I want to have sex with him all the time. But for some reason, it's really hard for me to achieve orgasms during sex. Whereas I have no problem achieving them when masturbating within a few seconds or a few minutes after watching porn. We've watched porn together too. When we're having sex, there's like a "meter towards orgasm" slowly going up. It feels great, but if he stops for a bit to readjust or if we switch positions, this "meter" resets completely. The only 2 or 3 times I've achieved an orgasm with him was during missionary, very fast-paced, uninterrupted and focusing on it. If I relaxed for a moment, I would lose the momentum. And reaching this point takes a very long time too - up to 2 hours.. (he holds back for me). One time though, laying on my tummy, there was this.. different feeling like I was about to orgasm (he was trying to finish me off with a dildo). The feeling was overwhelming - as if I was about to cum right the next second. I was very relaxed, I "let it go" like people wrote about it, but the orgasm never came, even after long minutes of this strong feeling. I feel pleasure in all positions but only missionary seems to get me close, and at some angles it's really painful. How come I can orgasm so quickly with myself, but it takes so long with him? And why does this "meter towards orgasm" reset if there is an interruption in stimulation? Is that a thing?

Although I am a male, I suffer from your same problem. For some reason I don't orgasm thru penetration. I give my girl orgasms by eating her pussy, and she loves it. I either get off by her blowjobs or handjobs. Like you, after watching porn I can orgasm pretty quickly.
I relate completely i can orgasm in inder 15 minutes masturbating. but even with my friend who is about 8 or 9 inches i can't seem to do it!!
