Recently I moved in with my boyfriend of four years. Everything is great between us and we have a lot of fun together and a lot of good conversations. Our relationship before this was always long distance because I was in college, and he even left for 18 months to take a job overseas. Some how in the couple of months we have been together the sex has dwindled down to maybe once a week at most. I am constantly getting turned down when I try to initiate anything with him. He tells me some lame excuse for why we can't do it or says that we will do it later, which never happens. Whenever I approach him about this he always tells me that I am using him for sex. It hurts my feelings to be turned down by the love of my life. What can I do to make him see that he is not satisfying my sexual needs?
