A real a$$ ? With stretch marks !? Das Betty ₿ooty
Why?
Growth marks ?
What, skin?
I think he is being ironic...
However, women usually don't like or fell unattractive having those stretch marks... Pregnancy or loosing or gaining weight too fast, with an non hydrated skin, makes those.

The body changes as it lives life....pretty common and expected
A real woman has racing stripes!
