PSA I guess: "No means no" applies to much more than just sex. If you ask if someone wants to do something, and they say no, then don't be pushy and say things like "oh come on, it's fun!" or repeatedly push them to do the thing. Maybe they know themselves better than you do?? If you're disappointed that they don't want to do the thing, then that's a you problem. All consent should be informed and enthusiastic regardless of the context.
