I have had a big butt since I was about 12 years old. It seems like it just of got bigger than the rest of my body all of a sudden. I am not fat but I have a small waist and a big bottom and thighs. I take after my mother who also has this body type. My sister who is 2 years older than I am is more slender like our father. She used to tease me all the time. When ever we would see a really fat woman with a hugh butt walking down the street she would say "That is what you are going to look like Karen." I have become paranoid and think that people are staring at my butt when I walk away because of it.
