too much sex??

so my man is like a never ending sex machine.. he will play 2- 3 times a day if we dont have sex .. he said he doesn't need sex every day from me , but it's hard to avoid releasing himself.. he can't go 24 hours.. I dont mind he takes care of himself ,but I feel bad because our schedule is crazy and I dont feel like doing gymnastics on his dick right before bed..especially since I'm 4 months pregnant and we have a 5 year old.I help him release whenever I can ..but it just feels like a job instead of enjoyment.. how do I get over this ? I want to enjoy doing things for him ,but every day feels so routine 😞 any ideas???
