How to get him worked up (advice please)

Hey all! We’ve been married for years now and we’re starting to get to that point in marriage where sex and foreplay start to become complacent for us. I am taking a bath right now getting all sexy for him and if it still fits (I’m 6 months prego) I plan on wearing some new lingerie for him tonight. What are some ways to drive him crazy and really get him going insane before we get to sex that you all love to do (other than head that’s an obvious one ) Thanks 😘
