Dating exploration – Hinge

I’m interested in exploring non-monogamy. How can I figure out whether it would feel good for me?
I’ve matched with someone who identifies as straight….and am feeling a little hesitant. Advice?
As a femme who's attracted to other femmes, how do I make it clear I'm flirting?
If someone doesn’t have their pronouns listed on their profile, can I just assume it’s they/them?
How do I express my boundaries around substance use without sounding judgmental?
How do I recover from accidentally misgendering while trying to flirt?
How can I start dating if I’m not ready to come out?
How can I help better affirm my gender in the early stages of dating?
