Hi guys, I have a really big problem and I don't know how to get over it. Let me start.

Since the beginning of my journey I've lost 45 lbs. I bought nice clothes, I trimmed my beard at 3 mm and outlined it, I waxed the space between my eyebrows (not much hair but still), I trimmed my nose hair, I got a nice haircut and removed my chest hair. I walk with proper posture and almost always smile looking at everyone in the eye.

I've noticed how my (girl) mates treat me different, touch me more, etc., and people straight tell me that I look really handsome now. For example, today I went shopping and noticed girls checking me out.

I like going to a disco where they play latin and dance music as well as some rock. I love dancing and I think I do it quite well and I give it my all the whole night non stop. Girls check me out, they come near me expecting me to go dance with them but I don't, and it's beginning to be a problem, because of the frustration of not having the balls to do it and because they attract guys and we end surrounded by 4 girls and 8 guys (that want to get the girls).

Today, I wore nice shoes, jeans and a V-neck shirt. Several groups of girls have come to dance near us out of the blue. I crossed sight with 2 different girls (never looking away first and always smiling) and 3 girls have straight come to rub their ass against me. I did nothing, actually I did, I just moved away from the girls that were rubbing against me and kept dancing, the girls that looked at me I never looked at them anymore.

I have this strange self-sabotage technique where when they are showing me their back I think "I can't go in and just grab them, I'd prefer to have them on the other side to look at them and smile and tell them to come with a gesture". But then when they are in that position I never look that way, and the few times I do, I don't make anything happen.

I don't know what the hell is wrong with me. It's not fear of rejection, some of these girls are literally rubbing themselves against me so I know they want to, at least, dance with me. But I just mentally collapse and try to find excuses to not go in. Too young, not hot enough, too slutty, well I love her eyes but I smiled her friend before, etc. They are so stupid yet they sound so good in the moment.

I'd like to know if there are any tricks to help me overcome this. I've already told my friend to punch me every hour that I haven't approached tomorrow, because I am going out too, but I don't know.

For the record, once a girl came to my friend, asked about me, my friend said, go ahead, and she started dancing against me and I didn't even touch her. Another girl came: "Hi! What's your name?", "Throwawaymilions", "Cool, my name is Laura", "Yeah these are my friends F1 and F2" and I left them, instantly went away. Another time a girl came: "Hey, why aren't you looking at me?", "Do I know you?", "Nooo", "Then", she just went away. Those are before my change, so you can see it's a problem I've been having like forever.

It might look like I'm boasting, but I just showed the "awesome" part to illustrate how infuriating is to have changed everything you wanted to, and still not being able to do what you want.

I know there is askreddit but this is not really a specific question with an easy answer so I thought I'd let this here.

Thanks guys, you are awesome!

TL;DR: Why don't I approach girls that I know want me to and what to do to overcome it.

EDIT: BTW I just read Models by Mark Manson and it's an incredibly helpful book but I think I haven't had time to assimilate it yet and need to reread it.
