Husband just doesn't have the urge.

Does anyone else's husband have no desire to have sex everyday? We will have sex (and he doesn't seem to even try when we do) and then if I try the next day he will turn away and tell me we just did yesterday or something along those lines. He'll come up with excuses and it just makes me mad. He's ok if we go some days/weeks without it but I'm not ok and he keeps saying he'll work on it but it always goes back to it. It's the only thing we fight about and I'm just fed up.
