Do you have trouble getting your husband to TTC sometimes?

Sometimes I have trouble getting my husband to have sex as often as feel is necessary to get pregnant! I try to stick to every other day during my fertile period but a lot of times he doesn't want to because we are so tired from work etc. I sometimes agree with him and am not really in the mood but I want to do it anyway... Just a quickie. Anyone else have this problem? Every other day can just feel like a lot to keep up with sometimes!!  Maybe we are just old lol. He's keeps saying "tomorrow" but I don't think he grasps how important "today" is.
