Thanks for the reply Skeezyks.
Yes, I've also read much about evolutionary psychology. I know that my desires are natural, that's not the problem. The problem is the overwhelming feeling that I will never be able to satisfy them.
It's not that I want some unreal, imagined goddess. Every day, I see dozens of women who make my heart race. But I see myself so inadequate that I can't imagine myself with them, only those who are sexually neutral to me. I also have a case of BDD (about my facial structure) which is the biggest cause of this.
Also for some time (about until I was 20), I thought of beautiful women as some kind of "prize" that are "earned" by men who "deserve" them (through hard work, strength of character, etc). It was then that I realised that women are just as simple as us, and for other guys (the handsome ones), getting the girls that I hopelessly salivate for every day is very simple. I started to hate myself for being so inferior, for being born into a body that cuts me off from what I want to experience the most in life.
