Well, I doubt this quiz was devised by anyone really qualified at such things, but it wasn't too far from my own self assessment. I've always rated myself at about 60-40 F to M. It rated me 67% Female, 33% Male. I guess I may be getting girlier with age.
PS- Elsewhere on that site, I learned that ... my mind is rated NC-17, guys think I'm too easy, I belong in London, my fashion style is classic, I'm a frugel grocery shopper, I'm like Kate from Lost and I should have curly hair with blonde highlights (I'm considering that last one).
