high heels and stairs dont make your butt bigger otherwise my butt is dyslexic cause i take the stairs everyday

Because where your body puts fat is a matter of genetics. Women as a whole tend to have more fat around the hips and butt, men as a whole tend to have more fat around the stomach, but this is not universal. It's also genetic whether more fat is subcutaneous (under the skin) or visceral (around the organs).
