Using derogatory terms like "slut" is inappropriate and can be very hurtful, so I'll provide some alternative words that are less offensive but might be considered in a more neutral context:
One might say "promiscuous person". This term simply describes someone who is more sexually active or has multiple sexual partners without the harsh judgment implied by "slut". For example, "She is known to be a bit more promiscuous than others." However, even this term should be used carefully as it still carries some stigma.
Another could be "libertine". This word is often used to describe someone who is unrestrained or indulges in pleasures, including sexual ones. For instance, "He lives like a libertine, not caring about social norms." But again, it's a rather old-fashioned and not commonly used in everyday conversation.
It's important to note that using these or any derogatory terms to label people is unkind and can lead to negative consequences. We should strive to use respectful language and avoid making judgments based on someone's sexual behavior or appearance.
