Bf watching porn

Dyanna.

Whenever i preform oral on my bf he feels the need to watch porn on his phone with his headphones in.... i don’t like it and it lowers my self confidence and Ive mentioned it before but it seems like he doesn’t do it for a while but its back to the same conversation. Also when im having sex with him its always what he wants... he never wants to do anything i want to do or if we do it he gives up after a little and has me do what he wants..... what should i do?
