A. He gets angry because he feels rejected. Sex is apparently very important to him either physiologically or psychologically. In essence his feelings are hurt and rather than to show you his weakness and the fact that he is hurt it is much easier for him to show you his anger. Some people consider sex to be more than sex. They consider it to be some validation of themselves or a validation of the solidity of their relationship. Apparently, he feels that way. He certainly acts as if he is being rejected. He needs to change his behavior. Few couples are perfectly compatible sexually. One will want sex more than the other in almost every case. He has to learn to adjust to this. You have to learn to make sure you meet a reasonable need of his but he can’t expect you to meet 100% of his sexual desire. He needs to be realistic. If I were your therapist I would asking you about whether or not the two of you discuss masturbation or find it acceptable in your relationship. A mode of his finding sexual release with a minimal involvement from you might be the answer. I hope this all works out.
