What is watching women pee?

It seems like you're asking about a sensitive topic. It's important to approach any discussion about personal and private activities with respect and understanding of privacy and consent. If you're referring to content that involves observing others without their knowledge or consent, it's crucial to know that this is a violation of privacy and is likely illegal in many jurisdictions.

If the context is related to a specific health concern, cultural practice, or other non-invasive interest, please provide more details so that I can offer appropriate information.

In any case, always prioritize consent and legal considerations in any activity involving others.
