@lerobshow,
I'm sorry this is happening. He sounds like he's checked out of a lot of the relationship and is just lurching from one porn video to the next.
I suggest couples counseling or at least a medical workup for him. And you should get checked out, too, mainly because (a) it would lead by example and make it less about sex and more about concerns for his health and (b) a lot of young men don't keep up with their health regularly so you might be due for a checkup anyway.
Because, to my mind (I am not a doctor), he sounds depressed.
If he won't get checked out, and he won't go to couples counseling, then I suggest going on your own. Get either a coping strategy or an exit strategy, because if he doesn't want to work on fixing things, then those are your options.
