I need some help with my husband.

I don’t have a high sex drive. I never have. My husband always told me that he didn’t care. Wasn’t a big deal to him. Tonight he tells me that he’s tired of being nice to me about it, that he masturbates 3 times a day to porn in the bathroom. This wouldn’t be a real issue for me if he would have talked to me about it. If it wasn’t so incredibly excessive. If he told me this is what he needed from me I would have tried harder to meet his needs. But now I feel worthless. He also told me the one time when I tried to initiate sex with him, he told me no because he had already masturbated that. What do I do? Don’t say divorce him because I really don’t want that to be an option.

Edit; sex with him is mediocre. He goes for less than 5 minutes and gets tired and stops. Never tried to get me off.
