im 16 and ive never grinded with anyone before until these past few days. everyone around was grinding and i didn't want to be one of the losers sitting around just watching from the outer layer of the crowd so i quickly tried to study everyone else to get the feel of how to do it. finally i went up to a girl and asked if she wanted to dance she nodded her head and put her butt on my junk and started dancing. theres only one thing that i didnt really know for sure what im sapposed to do, i didnt know if the guy is sappose to do most of the work or if the girl was. i think i screwed up big time with a whole lot of girls because they were dancing incredible at first then when i kinda started guiding her waists, she would just drop her arms. a few seconds after that she would walk away. im not really embarresed because i was at this teen club in the Bahamas and i will never see those girls again. i would actually call this just a learning session. im just trying to figure out what im doing wrong, and the correct way to make it extremely fun for both of us.
oh and another thing, when i was kinda guiding her hips, we would get off sync and they would start to get a little aggravated.
