Well, after reading a bit on here, I've been constantly focusing on being alpha. On every interaction I keep my mind about being assertive, confident, how is my body language and such. Afterwards I rethink it in my head and critique it to learn from it. I even feel comfortable talking to alot of girls now, I can talk to a group of them and lead the conversation nowadays.

There's a HB 8.5 in my class who I'd really like to go out with and so I'm trying the indirect approach every once in a while. However, I find that when I'm talking to her I automatically fall into chode/afc/beta mode. Have an example.

At literature class we were doing some classwork about a song. This HB8.5 was smashing the stereo trying to get it to work. I go up say "Let me do that", touch a few cables and it starts playing. I mention that said band would be playing for free on saturday. At this point she completely turns towards me (I was standing, she was sitting on her chair) and is like "OH MY GOD REALLY?". I tell her how I found out. She says, and listen to this: "Oh my god, I wanna go so bad!!". And do you know what I said? I fucking said "That's great, it's gonna be awesome", kept chatting and left. What the fucking fuck?, only two hours later did I realize the opportunity I had just missed. I'm sure with any other girl I would've spotted it right on, but with this girl I could be hit by a train and I still wouldn't notice.

How can I keep myself from being stupid around seriously hot girls?

P.S: I thought about it the whole following day and figured that the best way to deal with this situation is what I've done today: Talking to HB8.5's best friend (they're like two balls in a scrotum, never go anywhere without the other attached), I said "So what you gonna do about the concert?" She says "I don't know because parent's birthday yada yada yada" (lots of shit I didn't really care about) and said "Well, I'm gonna meet up at 'x' half an hour before the concert with some friends" (I didn't say see you there or wanna come. Stupid me). She just said "Oh great, thanks" and left.

Shit, this got longer than I expected.

Edit: Bonus question. How can I establish a sexual frame? Keep in mind I'm in highschool, so saying/touching the wrong thing on the wrong girl can have very bad repercussions, both socially and maybe even legally.
