This is a serious question.
Is there a correlation between the shape of a woman's pussy (innie/outie) and her voice?
If higher estrogen tends to lead to both higher voices and growth of the labia + mound, is there a tendency for girls with innies to have higher voices?
My friend says girls with outies have deeper voices. With one exception, I have noticed the high pitched girls have all had innies.
How could we study this for real?
This research would be revolutionary. You could choose your preferred pussy type from just a conversation with her.
