Best Ways to Get Him in the Mood?

I (31F) tend to be the kind of person who just says, “let’s have sex now!” He (45M) said that it would be great if I could sometimes set the mood – which I understand. With that said, what are some good ways to set the mood? I know I can always go up to him and *make moves* such as unbuttoning his shirt or kissing his neck, but sometimes that seems so weirdly out of place. Any suggestions? Thanks!
