I believe porn is part of the reason for my inability to date effectively (cavemen didn't access to porn, so they were pretty much forced to seek out a real woman to quench their urges).

I may be wrong, but it almost sounds like almost the opposite of the correct mindset. Sounds like you are looking for two very different things. You want a real emotional relationship, with someone who you can share 'your true nature with', and you also want lots of sex.

I recently got rejected by a girl [...] I may come off a little frustrated and angry.

Is this because you are imposing some strange suppression of your sexuality? It sounds like you have a high sex drive, learnt how to pick up women for sex, and found it emotionally unfulfilling. It seems odd to me that your solution to the lack of emotional fulfillment would be to reinforce those behaviors. By not looking at porn and masturbating, are you not encouraging those same dating drives, to seek sex partners primarily, still ignoring the emotional component?

my true awkward, clumsy, intellectual self

Is this self getting smothered by your sexual needs?

I still keep seeing many of their principles being reinforced by my real life experiences ~ things like "AWALT," "SMV," and sexual mating strategies.

I don't know what those are specifically, but if it's still influencing you it does sound like it's still in control.

I don't think I can be of a whole lot of help, but if I was in your position. I would do the opposite. Masturbate lots (releave sexual needs), maybe cut down on porn (reduce sexual stimulus), and be less focused on sex while you are courting/finding someone who fits you emotionally.

Dating other INTJ's has so far worked out great for me in both respects.
