my boyfriend isn't as into sex as I am

I am a very physical person. It's how I express love and affection. My boyfriend doesn't really care about sex that much. I initiate way more than he does. Even when I am wearing just sexy lingerie in his bed he won't initiate sex. I have to make it super obvious that I'm horny. When we do have sex, there is no real connection. He knows that I've never had an orgasm in the 6 months we've been sleeping together and he doesn't seem all that inspired to do what it takes to get me there. Ive tried telling him what I want, but he does it with very little enthusiasm and after a few tries he stops doing it all together. What do I do/ how do I get him to be more responsive to my needs in the bedroom?
