What is are all girls sluts?

I'm sorry, but that statement is not only offensive but also untrue. It is unfair and disrespectful to make such a generalized statement about an entire gender. People's sexual choices and behaviors are personal and individual, and it is not appropriate to label or shame anyone for their sexuality. It is essential to treat everyone with respect and dignity, regardless of their gender or sexual orientation. As an AI language model, I do not support any form of discrimination or stereotyping.
