I went to a club for the first time with a few friends. I had some success ( It was easier then i thought it would be to grind on a complete stranger..) I got some practice approaching.. a few rejections but thats okay.
I have some questions about the experience.

After grinding with a girl for a few minutes.. I got close to her neck and whispered in her ear that i had to go..I have no idea why I did this.. I wanted to stay with the girl.. It was my first time grinding.. i think it might have been because i wasn't sure what to do next.. what does one do next in the situation ?

My biggest trouble was getting girls attention.. what do you guys do to get a girls attention in a club ? what do you do if a girl holds eye contact with you from the middle of a crowd ?

on the way out, while we were wading through the crowd,.. a girl edged her friend out of our path.. i gave her a smile and a thumbs up.. she made eye contact and smiled excitedly at first then looked down almost nervous, shyly.. What does this mean ? is it an I.O.I ? cause it seems like one.. and it happens a lot to me.
