So, I've been reading a lot on club game, and one of the most important things is to make eye contact with the girl that you want to dance with.
Most of my friends said that it's just better to grind on girls right away, but I've read that it rarely leads to anything, so I've avoided doing that.

However, when I tried to make eye contact with the girls, one of these three things happens.
1. The girl makes eye contact with me and then quickly looks away. (she's either shy or she's not interested in me).
2. The girl makes eye contact with me for 3 or 4 seconds and smiles at me. Sometimes, they come up to me and say "hey" to me. After that, she turns her back to me. (I'm not sure if she's interested in me or not. Not do I know how I should act whenever a girl does this).
3. The girl holds eye contact with me for 10 or more seconds and she moves closer to me. At this point, I usually give her a handshake and we both remain eye contact. However, I don't know what to do afterwards, which I want to talk about today.

So, I have no idea how I'm supposed to dance with a girl if she holds her eye contact with me and wants to dance. If I touch the girl too soon, she's going to assume that I'm incredibly rough (one of my friends even jokingly said "Man, you should treat them like girls. They're not guys that can easily handle this.". I believe I've seen this on an RSD video as well). If I touch them too late, they're going to assume that I'm too cowardly to touch them.
Speaking of touch, how do I touch them? Where do I touch them? How long should I wait until I initiate touch? And before you're going to say "just don't think about it", I've been trying to do that shit for ages, but I'm still overthinking every little thing. And before you're going to say "just drink 2 or 3 beers", I'm the designated driver and I would much rather not rely on outside stimulation in order to get good with girls.

So, my question to you guys is this: How the fuck do I dance with girls at clubs?
