technically i have a tip but its not the one you think im talking about

Be yourself

but honestly im an introvert i cant help idk why im commenting

just be calm. just think you are just talking to your freinds. hope this helps! :)

finding common interest is great, allows you to talk more freely. Also try to be confident, but dont overestimate yourself. (this is from a certified single so take it with a grain of salt.)
