I have a serious problem.

I am addicted to receiving oral sex and when I do not get it, I masturbate. My urges are very intense and come about often. I would say maybe 5 to 6 times a day. I am currently in a relationship with someone who use to perform whenever I wanted but now he uses it against me. To prevent myself from stepping out of the relationship, again, I masturbate. I masturbate before work, at work at my desk, in my car on break, when I get home and before I go to bed. I am never satisfied. My partner doesnt understand or care to understand how this affects my life. I dont know what to do...
