How do I get him want me more?

You could (and I know this is gonna sound crazy, but roll with me) try talking with your partner.

I know, I know, I'm a maverick, but roll with me here.

You see, you are having sex with your partner. And (I assume) the sex is only between the two of you. Therefore, if you want to change things related to the sex you are having, the best thing to do would be to talk to your partner and maybe work something out.

Now, to be fair, sex is a thing that does peter out over time. Two years in is a fairly standard time for sex to become a bit of an issue. But the thing to do then is to communicate with your partner about the sex you are having.

If he doesn't seem into the sex, ask him why. If the sex doesn't last very long, ask him if he wants to change that. If you're not having sex as often as you'd like, talk to him about that.

Sex isn't a thing that just happens, you and your partner should be talking about it, making it happen and working on it. If you want to bring something new into the bedroom, you need to talk about it. If you want to do something different, you need to talk about it.

If you two want to have different amounts of sex, that doesn't have to me an incompatibility. Whether through fantasy, masturbation, or date-nights you can probably work something out that works for both of you.

You can't make your partner want you more though. You can't make your partner do anything and you can't restore that new-partner feeling. Instead, enjoy the increased compatibility, the knowledge of each other and the intimacy that comes from a long-term relationship.

Adding to the wise words of Jessiebelle, remember that the fire always cools. That doesn't mean he doesn't want you anymore. Now that you two have settled into the relationship, the honeymoon period is over--if not for you, it could be for him. But yes, to reiterate, talk to him, work on it, and everything will work out fine :)
