Should I plan?

My partner always drops hints about wanting a baby and constantly says lets make a baby or  when we wake up he hold my stomach and asks if there is a baby in there but he gets major freaked out when we have the convo or even when he has to plan anything. He says it's too much pressure. Confusing huh! Should I just let nature run its course? Does anyone else have similar problems with there man and not liking to plan things???
