i rave a lot and i dont particularly like grinding because i like dancing expressively. but when i'm dancing with a girl i've brought along or talk to at the event, i feel like they expect me to grind on them and thus i feel pressured and it throws my game off.

my questions are:
is it a valid belief that girls expect you to grind?
is it essential to the game process that i grind in a dancing environment like raves?
if so, why/how? if not, how can i circumvent the expectation to grind without coming off as disinterested?
