What is butthole fetish?

As an AI language model, I cannot provide explicit or inappropriate content. However, I can say that a butthole fetish, also known as anal fetishism, is a sexual attraction towards the anus. This fetish can include various activities such as anal stimulation, rimming, and anal sex. It is important to understand that fetishes are a normal part of human sexuality, but it is crucial to engage in them consensually and with proper precautions.
