I've got a good bit on some high school stuff, just stuff that I've thought about and learned over the past few months. Some of it may be more relevant than other parts, but I feel like it covers a good range of stuff.
Something everyone in high school should do is build up your social circle. Before the year started, I hadn't really hung out with girls in quite awhile, it was really just my guy friends that I was hanging with. But I started talking to some more people, getting to know some of my friends' friends and other people. I've built up my social circle some, so I'm going to more parties and gatherings. Try talking to as many people (not just girls), as possible. This will help you make more friends and get to more parties. Having a lot of friends, talking to a bunch of girls, and going to parties helps you get both social proof and pre-selection.
Another thing that is really important is fashion and dressing nicely. Take a look around school, and tell me what you see most guys wearing. Not all, but a lot of them (at least in my area) are wearing t-shirts and athletic shorts with basketball shoes. Or when it's cold, big sweatshirts and sweatpants. Even some of the better dressed guys aren't all too-well dressed. I used to dress somewhat like this, but now I've started wearing button-downs, nicely fitted jeans or khakis, and nice shoes. And I've got a really nice leather jacket that definitely gets others' attention. I've gotten compliments for how nicely I dress, my jacket, and more. I'm telling you guys, it's something that is so easy to get down, but so many kids at school just don't. Just doing that gives you an edge over the majority of other guys. Combine that with good posture and a powerful and sexy walk, and it's killer.
Like Travis said, deep-diving and touch are very important. One more thing I'd like to add is EYE CONTACT. I've had a couple conversations with some girls pretty recently, and pretty much the whole time we were staring into each other's eyes. One of them was in the classroom, so it wasn't like I could escalate with her right there, but we were in our own little bubble the entire time. It was one of the first times I had actively and consciously tried to employ eye contact, and its power amazed me. It almost felt like we were in a trance. Another one was at a party, and while we were talking we were maintaining contact the whole time throughout. It just upped the tension a whole 'nother level. I was also using touch pretty well, and we were getting really close. It would've gotten me a hook-up had it not been for us getting pretty drunk and a couple of our friends watching us the whole time. I feel like I'm rambling a bit, but seriously, eye contact is gold.
As far as logistics go, that is something that seems to be causing me some difficulty as well. Parties can be pretty easy ways to get fast hook-ups if you've got your fundamentals down. But in terms of escalating with a girl you are just meeting during school, it might not be best to go to a party with her. It sorta depends on whether you have a car that you can drive, how understanding your parents would be having girls over frequently, and where you live. But ideally, you get her on a date, bring her back home (knowing that your parents are gone or won't be noticed), and escalate from there. If your house is not an option, you can always try to find a way to get over to her house. And yeah, a lot of girls will move more slowly, so in most cases it will be difficult to get first-date sex. But it can always happen, so keep persisting.
Let me know what you guys think.
Cheers,
