Sex Talk!!

Basically my partner is having less and less sex w me the farther along I am. We used to have sex 2-3 times a week, now its not even a week sometimes!! And I know when I am at work he’s watching porn and it just makes me so insecure!!!! I literally crave sex and him and its like what do I even do at this point. Ive talked to him about it previously. Should I just not have sex with him for a while, I am getting annoyed!
