Not enough sex!

Ever feel like you need more of a sex life? My man works hard mon-friday but he has massive baby fever. I feel like we hardly have sex though :( and it really bums me out. when we do he's all "oh we can have sex tomorrow " or he's tired! It's like he has to plan it and always only when he wants it. I need that connection with him. We have no relationship problems at all and can stay up chatting all night. I love him. Am I overreacting? How do I fix this? Can this be fixed? How are we supposed to make a baby if we hardly have sex? Last time was 22days ago. Am I nuts for being mad?
