How to use OMGYes as a couple

So I’ve bought all 3 seasons on the holiday sale. I didn’t have a goal it just seemed different and interesting. Had a quick skim with wife, she isn’t immediately too interested in using it on her own, but she’s up for doing stuff together.

So what are some ways people have successfully used it or have had fun with it as a couple?

Edit: 35-ish straight married couple. Sex is good (albeit a little infrequent due to kids) but always looking for new things :)
