Nowhere on the app does it ask you for your sex. If you were so afraid of your application being viewed differently because you are a woman, hiding that fact on the app is as simple as using an alias and answering the questions without saying 'OH YEAH, AND I'M A WOMAN.' And if you think any of those at YC, whether pg and gang, or the alumni, would 'dock' you on points for being a woman and overlook your potential and that of your idea, you yourself are being sexist for assuming that a man would be so irrational and illogical for the sake of gender discrimination.
And sorry for being harsh, but don't pull that 'they don't relate to me' crap. We're all aspiring entrepreneurs trying to make it out there with our ideas, connections, talents, etc, and any decent person would judge you on such. I don't need a pair of breasts and a rush of estrogen to relate to you. You're perpetuating the same gender gap you are criticizing others of exploiting.
I know you're a woman, but man up.
