My boyfriend [38yo] barely looks at me during sex

I have had a constant battle for over two years about my sex life with my boyfriend who is now 38. I know that he is insecure, however I don’t feel connected to him at all during sex. He hardly looks at me, his eyes are closed and always has trouble maintaining a you know what. Recently, I found prescription ED pills that he’s been taking. He doesn’t know that I know and now gets hard before we even start foreplay. He still doesn’t look at me much during sex and I am definitely not an ugly girl. I don’t know what to do. I don’t know if he would rather watch porn than have sex with me or if he’s just so insecure, it hinders his ability to be intimate and close with me. We have had many conversations around sex and I have voiced my concerns however he takes it as criticism and turn gets more insecure. Help. Sex is a very important part of a relationship for me and I am worried that it will be this way for the rest of my life not to mention we never do it any other place other than the bedroom theres no spontaneity at all.
