because, even though she has her "on" days... I think most of those were years ago and more often than not these days she ends up looking like a drag queen.

I don't like the 0% body fat look. She's just a little too hard-bodied for my tastes. I like skinny girls, but Kobe just looks like she has no soft tissue at all. Pure bone and muscle, except for her tits, which look like two sad partially deflated water balloons hanging from a fence post the day after a party. Her jaw is a little too strong, her face a little too crevassed and leathery, her makeup a little too liberally applied. Plus she just looks slutty. I know she's a porn star, but I know plenty of porn stars who don't look like tramps all the time. I'm not even saying being a slut is a bad thing necessarily, but do you have to look like one?
That said, I do like petite, fit, sexy asian girls. I thought Kobe was really hot when she was in the movie "Very Bad Things." But these days, there are literally hundreds of other asian adult film actors out there that I think are much sexier.
