You don't have to implement the full feature. Try a prototype version that is intentionally smaller to see how "fun" the mechanic is. Then go fork of the other prototype mechanic and test it. Because both are prototypes that are deliberately small in scope, you won't feel bad tossing them when making the "real" implementation.
I've been having really good luck with using ChatGPT to push through my various walls. Oftentimes it will at least give me a rough idea of how to do things I'm too gun-shy on or, even if I don't like the answers it gives me, the act of writing out out my concerns/struggles/plans/etc helps me sort through my thoughts better and gets the ball rolling. I use it like a rubber ducky that answers back and gives some decent answers from time to time, basically.
Welcome! Good luck! A thought: Because I do lewd stuff, I do tend to have to use metaphors and abstractions for my conversations, so I don't have to worry about sharing any private info. You may wish to do the same for privacy/security.
