ok so i finished high-school this week and there's a HB9 that were in my class, we had a pretty friendly relationship during high-school and yesterday we had a really deep conversation for like 75 minutes and she gave some IOI's and i know that altough she is really hot she is lacking experience.. i find her attractive but how do I convert our relationship to a more sexy one than a friendly one?

You built (a lot of) comfort and trust, now you need to create attraction.
If you escalate without attraction, you are going to hear "Let's just be friends".

The good news is that "attraction isn't a choice", you "just" have to trigger an old circuit of her brain. How? By DHV, social proof, preselection,...

* Keep contacts with her but don't become her "best friend" or confidant, don't call/text her every day. Currently, she is just "one of your bro's". You are officially not attracted to her and you use to know a lot of fun HB9's (or fake it).
* Become the "social motor" of the group. Go out and invite a mixed group of High-school friends (including her) and use these fun moments to DHV. You are the "tribal leader".
* Make some casual activities with your target and try to slowly escalate. Begin like you have a casual drink with your "HB9 bro" (you don't date a bro, right?). Then you have to create sexual tension till the kiss (and more) "just happened".

Rule #1: YOU are the prize, YOU are the selector, don't fall in AFC behaviors

PS: You have to know that a lot of women only understand that they are attracted to you when they feel it. A little bit of jealousy is a great tool for PUA.

Do you even know you are in the friendzone?

I don't think you are just yet. Therefore you must state your interest boldly and unapologizing. "You know I think you're cute"...whatever. Tease her, make her laugh, state your interest, don't take her shit. If you are absolutely certain she likes you, giving you a lot of IOIs, then game on. You can assume attraction and go in with that mentality of "I know you want me, whatever you say".

ok so today i met her again after we made some "gradtuation parade" all over the city with our cars... and we finished it at the beach then i first saw her, she was hot as hell in her bikini and i just came put a hand on her wrist and said what's up? she said she's fine and that she just asked my best friend where i was? i did'nt open any conversation and then i asked this good friend of mine if she asked him where am i and he said she never said anything like that... wierd shit? why would she lie to me that she was looking for me if she have'nt? should i not communicate with her at all and wait for the party that she would be in next sunday night and there just dance with her a bit and escalate some kino with no fear and go for k-close in front of all of our friends? the problem is that we were classmates for 3 years and it's hard for me to belive that she's attracted to me cause nothing happend all those high-school years...
