Idk how to feel...

I found out my boyfriend has started watching Porn again and beating off. This honestly wouldn’t bug me at all except that once again, he beats off but never has sex with me. He says he doesn’t have a high sex drive and is never in the mood, but he beats off? Then when I ask him to have sex with me and he says no he gets upset that I get sad. Physical touch is my primary love language. Intimacy is a big thing to me. I want to feel wanted and desired, but it’s also how I communicate my feelings to him. So yeah I do get sad when he says no. Then he said it hurts his feelings when I get off by myself in my room. I just don’t understand how he never wants to have sex with me, but gets upset when I get off by myself. I don’t care if he got off by himself if he had sex with me at least occasionally, but he doesn’t. He also said that he sacrifices his feelings to have sex with me just to make me happy. I don’t want him to “sacrifice”, I want him to want it too, I want sex to mean something, but he says it’s just fun to him and doesn’t mean anything. It makes me feel so worthless and unattractive. I’ve tried talking to him about all of this and he gets super mad and starts a fight and starts yelling at me and calls me a slut and stuff. I’ve honestly just given up. I’m done asking him for sex and I guess I’m done getting off myself. It’s a lose lose situation for me.
