Quoting DoulaLC
The problem is not really that you don't climax every time, it is that he gets mad at you for not doing so. I think he sees it as an indication of his not being able to satisfy you and that makes him feel vulnerable... and he takes it out on you.
Couldn't agree more. The pressure in feeling you HAVE to orgasm, is in itself a problem, and will make it more difficult to. It's the same with blokes! There's been an occasion where I've gotten sore or impatient, yet as I've hinted it to him, it's ended up taking longer.
I wouldn't worry darling. In fact, I've NEVER had an orgasm during sex. I've been doing it manually and externally for about a decade! (Sorry, I know. Younger than most.) But it's only as I don't rate it as highly as the romance, passion, and amount of things done. (exotic positions and foreplay)
He shouldn't get mad. He has no right to! Especially as assumingly that's not the only part he gets pleasure from during sex. If that were the case, he's very restricted when it comes to sexual satisfaction!
