Don't think I really have one. If you read The Life of Reilly, that would be my perfect life. With three differing girlfriends, all of them hot, and smart, and with different personalities. I don't think anyone really has just one 'type' of person, either in terms of looks or personalities, that they're interested in. When people are asked, they mostly describe their ideal, which is generally a pie-in-the-sky fantasy largely unobtainable. And this is easy to misconstrue.
A friend of mine recently told me I should lower my standards in women. She had the idea that I was always looking for a petite young blonde (much younger than me) with perfect body. In point of fact, most of the women I run into are younger, and have been for the last decade or so. But while I do like blondes, the hottest women I've known were brunettes, and I have a thing for redheads too. So you see, there really is no "IT" girl as far as I'm concerned. One thing I've learned is that if you can't sit across a table from a woman and talk for hours without getting bored, she's probably not for you regardless of physical attractiveness. At least, not for long. Maybe that comes with age. The days when the only thing I looked for in a woman was how hot she was are long gone.
And I think, to some extent, that's reflected in my books. My earlier books basically presented the female characters as a collection of physical attributes, while now I do my best within available time to give them characters, and make them seem interesting and like people I'd like to know in real life, to give them hopes and aspirations, fears and doubts. I don't always do as well at that as I'd hope but I think I'm improving over time.
