I refuse to be clear about my gender, because deep down in side, I want both. Assign me whatever gender you think I deserve.

Though, I think some of Perro's other statements might be false there. Yeah, I've worked with large financial institutions, but it's been a long time and never in terms of web security.
EDIT: I'll expand on that.
People make assumptions about gender. If I said I was a guy who writes this type of thing, you'll get a different impression than if I'm a woman who does the exact same thing. For some, it is hotter one way or the other, but the preconceptions changes how I'm viewed. And, no matter what is or isn't dangling between my legs, I lose. I can't make everyone happy, though I desperately wish I could.
Choosing to be neutral, while not very satisfying, is an attempt to be that middle-ground. Some people assume I'm male and others assume I'm female. I happen to love that, mainly because I don't strongly associate myself with either gender but I'm in love with both. I'm a fence sitter, both in my desires and my thinking.
Yes, I have a physical gender. I can't say I'm 100% happy with it; then again, I'm happier than most. But, regardless of the sexual characteristics given to me by the genetic lottery, the person who writes on this forum, who creates these stories, and has talked with you for years is me. Just a me stripped of physical body and just the thoughts in my head.
I'd like to just whip up a picture and throw it online, but it then forces me to be one or the other. I can't be Schrodinger's Cat, in that state of being both male and female, if that field collapses.
And, I like the idea of being stuck in a box...
So, I want to be both and neither, one or the other. I can be that here. Yeah, someone might decide that I'm full of shit and just move on, but that's okay. All of you have some mental image of who I am. I can never be that person. Period. I'm not as pretty, intelligent, or amazing as the image built up in your heads. So, I don't want to ruin your perceptions of me any more than I want to be jammed into some gender-specific corner for the rest of my online existence.
