I want more sex, help!?

My boyfriend and I have been together for about 7 months now. The sex is already sparse and stale.

He said sex isn't something that he thinks about a lot or is very important to him. The problem is, I think about it all the time and it's very important to me. It's fun obviously, but it also helps me connect.

We've talked about it before and he says he'll try to initiate more, but that only lasts for a week or two.

We just recently went on a dry spell of 5 weeks, ... I was waiting for him to show me he was interested but he never did. I had to make the move.

And getting things started isn't easy... He doesn't like kissing a whole lot, he doesn't like me kissing or licking his neck, and he doesn't respond to me rubbing his thighs. To get the idea across to him I have to just grab his junk and rub... not very romantic.

So basically what I'm asking is:

How do I get him to want sex more?

What else can I try to initiate sex?

What would you do in my situation?
