I actually managed to get some experience on this even though it may be an obvious concept but you wanna always be trying again later if your advances fail. Let's say you're grinding with a girl and after a while you go in for the kiss but she turns her head away. Don't try to force it, in fact if she starts turning her head, immediately retract and play it cool and go back to dancing. If she doesn't instantly leave then chances are she doesn't mind making out with you it just has to be the right time.

If your initial move failed then just give it some time and try again under different circumstances. Maybe the song changed and isn't upbeat anymore. Maybe you guys aren't dancing as wildy anymore. You just wanna have these things in the back of your mind. Most of all just have fun dancing/grinding.

A situation like this happened to me when I tried to go for the kiss and she turned her head but later on the beat of the song changed and i looked down at her from the side and tried to slowly bring my fingers up to tilt her head to mine and as I was doing this I think she realized what was up and between the time i failed last time to now she made up her mind that she wanted to make out so we just went at it. I think the first time when you go for the make out it's bound to fail because it's sudden and the girl is totally not thinking about kissing at all, yet you are. Then you try, she may reject, and then starts thinking and considering if it were to happen again what would she do. That's how I see it anyway.

Also, another tip is to not be overly forceful and needy about this. I remember afterwards I wanted to make out a second time so we were dancing for a while and I tried to go in like last time but it didn't work this time. Later on I tried again but I kind of tried to read her response after I made small advances. It's hard to explain but I just did it all as it came to me, we were grinding and the music changed and I was looking down at her from the side kind of and I tried to bring my fingers up again to tilt her head to mine but as I was doing it I saw that she was kind of resisting a bit like before. So before I even got to touching her head, I retracted my fingers back slowly and thought, alright this isn't going to happen because she's obviously not feeling it so fuck it, and then suddenly she turns around towards me and we start making out.

Was a strange situation but I think because I wasn't overly pushy with it, it worked anyway. I could definitely see this failing if I just kept trying to dive right into it regardless of her reactions.
