Women's Ass Size Study There is a new study just released by the American Psychiatric Association about women and how they feel about their asses. The results are pretty shocking: 1. Only 5% of women surveyed feel their ass is too big. 2. 10% of women surveyed feel their ass is too small. 3. The remaining 85% say they don't care; they love him; he's a good man and they would have married him anyway.
