Partially flat butt! iin?
So my butt is nice and round... but (pun intended)... there is a "flat part" on one cheek! The flat part is near where my butt becomes my leg. It almost looks as if it got flat from me sitting on that part for too many years. It was just round before and I've noticed the flat part about a year ago. I'm a female, early 20s, and thin. It's not really noticable but it bothers me. IIN?
