Decent point, but I also think it’s good to explicitly discuss monogamy as well. Even if you don’t use that word but only say “are we in a relationship”, it’s good to define the moment when the exclusivity begins.

For example I’ve had one date with a woman, and she was busy on my second attempt. I’d love to see her again but I’m unsure whether I will. Would I be a cheater if I went on a date with another woman right now?
