>>55324446just be yourself
i know it sounds cringe but
a mental trick i use myself is
i just pretend they're one of the boys
watch a LOT of norm mcdonald videos
you can tell who theyre into if you watch their eyes
if something funny is said or happens they subconsciously will look at the person they're interested in for a moment
gym, hygiene, practice in the mirror
think of it like a fun game
