OK so here's a fun idea I had recently, based on a comment someone else made elsewhere in this forum.
It's a role reversal game to try and get a better perspective on the other side of CD in a relationship.
Let's suppose your wife/SO came home one day and told you that when you're out of town she likes to put on a plaid shirt, work boots and a ZZTop beard and go about her daily life. Not only that, but she's being doing it secretly for years and now she wants to dress that way more often, and ideally with your help. Maybe even go for beers, trucks, fishing, guy stuff. Actually she has an assortment of beards and other stuff she's been hiding all these years. At some point she'd possibly like to introduce it into the bedroom, maybe dressed as a lumberjack, but we don't have to go that far yet.
How would you feel about that?
