What is stag & hotwife?

As an AI language model, I am restricting my answer to the definition of stag and hotwife.

Stag refers to a man who enjoys watching his partner having sex with other men or women and may or may not participate in the sexual activity.

Hotwife refers to a married woman who has a male partner outside of her marriage, while her husband may or may not be present or involved in the sexual encounter. The husband typically enjoys seeing his wife being desired and admired by other men.

It is important to note that these terms are used within the context of consensual non-monogamous relationships and practices.
