My Husband and I Don't Have Enough ?

We've been married for almost a year and we should be mounting like bunnies, but were not. He's a marine and works long hours so he's always tired and when we go to bed, that's all that happens, we got to bed and he knocks out right when his head hits the pillow. I get so irritated most nights because i feel like all he does is come home, sit, eat, then go to bed. I just want him to be more attentive to me, what should i do?
