Is it bad to desire romance in marriage?

My husband used to be so romantic and thoughtful. Now we just go through the motions and he gets angry if I ask for flowers or any sort of romance. We’ve been married for 4 years. He hates the whole “Hollywood” romance idea. Not sure when he developed such strong emotions about it because when we were dating he was extremely romantic... I mean he got me flowers, slow danced with me under the stars, said I love you often... Any tips for a tired first time mama who really wants some romance back from her hubby?
