You can get an app on your phone where you each get a tick list of things you’d like to try, and then it shows you all the things you matched on (and keeps the non-matches to itself 
). That could be a good way of starting off a conversation?
I can never remember what it’s called though. 
I’ve done this several times now, so hopefully I can find something in the Search.
Edit: Desire, Spicer, and Kindu. Kindu got a couple of positive responses.
