Bulge size options for character creation.

[NessaWyvern]

This is a picture of a character with muscle tone but yet does not have any butt to match, thus being unrealistic.

People with leg muscles and muscle tone also have butts. She does not have a realistic hip-to-butt ratio, and hardly any muscle in her glutes, despite having other prominent leg muscles.
This also applies to highlander females as well, and all female characters really, when you consider how active they are, and how wide their hips are.
