sexually frustrated w/ my bf

Zoey💞🌻
This might be kind of long so sorry in advance... My boyfriend and I have been together for 2 years. I've been pretty sexually frustrated for as long as I can remember. I am always super horny and willing to have sex... he is not so much. He never eats me out and if I initiate sex usually he acts like he's not into it. We've talked about it so many times and we've come to the conclusion that it might be because I'm too available and sexual all the time. I never make him work for it. Lately I've tried to be less sexual and it's only worked a little.. basically we just have sex way less and it frustrates me. Any ideas on what to do??? (Also another thing I should mention... I see in his phone history that he watches porn a lot. Regular and transsexuals.. we've talked about how it bothers me and he's cut back but still watches it. Help)
