If there's no way to deal with that flattening of her rump when bent over like that, you might want to give her privates a bit of range of motion towards her body, so things don't poke out quite so far when she's moving back and forth.

Not speaking from any practical experience with the program; just saying what I think might help with how far her bits stick out as she's moving.

Yeah im still new to blender so thanks for the tip!
