I'm sorry to hear about the emotional and physical pain you have been enduring. I can't imagine how hard it must be to endure the emotional pain of being made to feel as if you are disgusting by someone you love.

It sounds like you have communicated with him your wants and needs, and the fact that he either ignores your statements or brushes them off with a "joke" leads me to believe that he just doesn't care—either about your emotional and physicial well-being, or your pleasure. He sounds like a callous person and a selfish lover, and if I were you I would end the relationship and leave him. There is nothing wrong with you, and you deserve someone who doesn't make you feel like there is.

I wish you the best x
