I thought I would put this out there because this is what I did in college to combat the fact that I felt woefully unprepared for the sexual marketplace in any way. This felt unethical to me at the time because of BP programming, but nowadays I actually think it might have been the best decision I ever made. I sort of discovered elements of plate theory on my own and remade them to fit my personal circumstances.
This is specifically for men who are circulating around what I would call the "nerdosphere". In this case, I define "nerdosphere" as a group of men and associated women that would be classified as nerds who are socially isolated from mainstream partying and generally have limited social interactions with others outside of said sphere. I'm talking about a league of legends team, those kids that play dungeons and dragons every friday, people that generally don't party in the traditional sense, etc. This is inevitably a reductive concept but you should have an innate sense of what I'm talking about and whether you are in this sphere. If you are, it's fine for now. Long-term you will have to leave but in the short term you can use this sphere to your advantage.
Your first goal is to assume a position that I will call "King of The Nerds". Being a leader amongst nerds is actually fairly easy if you put your mind to it. But getting to that place does require a big shift in how you view yourself. You may or may not already be a major driving force within your nerd friend group, but either way, you need to begin to distinguish yourself. Obviously the basics like lifting, fashion, generally taking yourself seriously, and internalizing RP texts like The Rational Male etc are critical. Dressing a little better than your nerdy peers, going to the gym frankly at all, having RP consciousness. This level of reinvention is not always easy but, it will put you in a sweet spot where you will still be seen as part of the nerd sphere (because you were and probably still are), but you are a solid cut above your immediate peers.
Now at this stage, you face a potential pitfall. A lot of men will now be seen as safe beta options by some slightly above average women. Nerds, being especially relationship naive, will often immediately transition into an LTR with little to no prior experience because of BP programming. This is the "monogamy as goal" issue that Rollo discusses in TRM, and this is a horrible idea. Do not do that. In most cases, they end with the girl breaking up with you in like 4 months when she gets bored of your beta behaviors. Instead, built a plate portfolio of nerdy girls.
As naive and exploitable as young nerdy guys are, nerdy girls can be quite naive as well and starved in some cases for male attention. When you interact with these women as "King of The Nerds", you are in a position of power, you are the prize and you stand to profit quite a bit. She has so few orbiters that pale in comparison to you that she is limited in her emotional and social ability to mess with you. I have found that from this position it is much easier to establish frame, deflect shit tests (yes even nerdy girls do this), etc. In essence, they are an accessible proving ground with few risks for you. Now, of course, these women may expect or want monogamy more than the average woman but as long as you keep them at a slight distance this should not prove to be too much of an issue. Don't expect quick sex or in some cases any sex from the majority of them, but that's kind of not the point of this exercise. If they have competition anxiety that will push them about as far as they are willing to go, but again you are the prize and are at the center of it all and you want to cultivate that mindset. This would be the optimal time to lose your virginity; in a scenario strongly tilted in your favor.
By the way, this kind of goes without saying, but all of the "dates" that you plan should be within your parameters. Only do activities that you actually want to do, only do activities that fit into your schedule, etc. You can get away with quite a lot with nerdy girls from a position of strength and its better to exert influence than not just to be "nice". Build good habits. For instance, I've had women who were willing drive 2 hours to meet me somewhere before. Every hoop they jump through for you builds YOUR self-confidence.
If this all goes well, congrats you are now a contextual alpha. Transitioning out of the safety net of having mastered nerdy girl game is quite scary at first, but it is well worth it. You may need to undergo a second phase of self-improvement at this time. You should now be targeting women who are "nerdosphere" tourists. These are women who are generally reasonably attractive who happen to float around nerd groups in certain circumstances. I'm talking about that semi-hot girl in your bio lab that has like 30 nerdy male orbiters. These are generally the women that nerdy men feel are accessible enough that they are worth orbiting but are still attractive enough to idealize. You should also be trying to diversify your friend groups and trying to socially break out of the nerdosphere. These women and some new male friends should serve as a plank to transition into new social environments. After this transition, RP and hard work should take you the rest of the distance.
