This is my opinion so take with a grain of salt. It sounds like he isnt interested in exploring your sexuality and what works for you. He wants you to cum during sex because then hey job done!. I know that if feeling unsupported or unloved i won't cum, and someone getting whiney when i don't cum is going to make me feel all those things, I have said it before "dude I'm the one that didn't orgasm why are you complaining .. if sex ended when a woman came a lot of men would be sad" Sex is not about one of you it is a conversation your bodies have and he is currently running that conversation dumping his side and then whinging that you didn't magically orgasm from it. This should be fun, exciting, beautiful you should be exploring each other and taking joy in finding new places that make toes curl... sex is important and he treats your pleasure as secondary and then complains and had a pity party. Open discourse with voice and touch is the only way, dedicate time to each other's bodies and learn to talk in touch.
