Its kind of funny about size. Before I got married I would not date girls fit a certain image. Dated just about every cheerleader in highschool. When my wife was pregnant for the first time she of course got very big, but I still found her sexy. We had sex up to the day she gave birth. It always kind of struck me in a humerous way that I would not date large women but then after I was married found my wife sexy even when she was way way way fatter than anyone I would have ever even noticed before.
After that I found a wider range of women attractive - far from the typical cheerleader image. Tall short fatter skinnier - all types can be sexy to me now. Its more the way they carry them selves, the look in their eyes etc.
