Why Pinning Down Aesthetic Attraction is like Herding Cats

For me, my lack of being able to pin down whether I found someone attractive or not was basically what led me to identify as asexual. I'd look at a conventionally 'hot' guy, and think they looked okay enough, then double-take and not be able to understand why. It was very ephemeral; blink-and-you-miss-it, type of thing.

Even now I'm aware that I don't have a broken sexuality, just a lack of one, it's still very hard to pic down. When look at pretty people, there will be something about them, but there's none of the 'phwoar' my friends express when they see a 'faaaine individual'.

I don't have a type, or at least, I think not. There are a far-ranging and wide list of things I find awesome, but it's by no means a list or a type. And without sexual attraction I'm pretty much lost, because I can't be sure if the 'pull' towards a pretty face is actually there or not, because whenever I focus on the elusive feeling, slips away from me, like jelly in my fingers.

How do you feel about aesthetic attraction?
