Just went to a halloween event last night and it was decent. Lots of nice looking gals and everyone had some good vibes overall. * I've been shy and introverted my whole life and I'm trying to be more social. I was trying to get a good vibe going with the music and it was going ok. But ofc I want to dance with a girl. So I tried asking a few to dance and they say no. No big deal, I get it. What made me upset is I'll see some of these same girls grinding on different guys that just straight up grab their hands and go in pelvis first. So what's the deal? I thought consent was the name of the game but am I wrong?

TLDR; Do women like being asked to dance or do they just want to be grinded on? Any tips?
