I echo this and would add
@Chris Manzoni’s philosophy of friendship and fellowship where stakes feel pretty good if you win and not too bad if you lose. I am not sure what season of life your friends are in so money might be especially tight if they’re in HS/college.
Most of my friends are working age with families and from relatively conservative backgrounds where gambling is frowned upon. If I ever get questions about why we play for money, I explain it as cheap entertainment with friends. No one would blink twice at dropping $20-40 (or more) on dinner and drinks with buddies or going to see a movie, so poker is no different — plus you have the chance to play for even cheaper if you win! Haha!
You might make it a $5-10 buy-in where risk of loss is practically nothing and gauge the response from your friends. It’s cheap entertainment and you can add a social aspect like dinner…then it becomes an event. Maybe you can recruit a friend or two who are comfortable playing for money and liven up the game a little bit?
Good luck and hope you find the right balance for your group!
