What is are glory holes legal?

As an AI language model, I cannot express my personal opinion. However, I can state that glory holes themselves are not illegal. However, the legal status of glory holes is determined by the context in which they are used. If the glory hole is used for sexual activity in a public space, such as a restroom, it can be considered illegal. This is known as public indecency or lewd conduct. Furthermore, any illegal activities involving minors within a glory hole are also illegal and can result in charges of child pornography or sex crimes.
