Personally, I believe the "ideal size" is just an average desire of body shape. For example, nearly all of you ladies have opted for a slim hourglass figure. Personally, I'd rather be a rectangle shape (I'm an inverted triangle and could pass off as an NFL player). I know someone who has an hourglass figure, with huge breasts (they look like a C/D, but who knows), very large hips but a very slim waistline. In your eyes, that would be an ideal figure. But most of the boys find it quite a turn off. But there you go, opinions.
