Sex has everything to do with feelings. If you, the woman, don't feel as though your husband is treating you well or respecting you, you aren't going to be "into" the sex. Why should you be?
Maybe making porn a "together" thing would be a good idea?
I wish you both the best.

Why would I want to do that? I don't even want him to touch me the way he has been treating me? I would have some other man touch me though.....

I wouldn't be into sex with someone like that either. To be turned on you need to feel safe and you need to feel important to that other person. (at least for me anyway) And in the situation you are in, I would feel neither.
