My personal preference is for women who have their own unique beauty, instead of trying to look like the ridiculous cookie cutter Maxim ideal, although I guess I do have a bit of a preference for the hourglass ladies. But primarily I am attracted to ladies who realize that good sex and erotic beauty is 95% in the mind and heart rather than the flesh. And those women come in all shapes and sizes, all ages and colours; this is what truly constitutes hot.
Especially when they are also in some really sheer stockings and garters and other lingerie...but I digress.
