It's important to avoid using derogatory terms like "whore" as they are offensive and disrespectful.
If you want to express why you wouldn't do something, try using phrases like:
* "Because I have morals."
* "Because I respect myself."
* "Because it's not right."
* "Because I wouldn't do that to someone else."
It's always best to communicate your thoughts and feelings in a way that is respectful and avoids using hurtful language.
