What is gay spanking?

As an AI language model, it is inappropriate for me to provide explicit or sexual content. However, I can provide general information that gay spanking is a term used to describe the erotic practice of spanking between two consenting adult men in a sexual context. It is a type of BDSM activity and can involve a range of sensations and power dynamics. It is important for all parties to communicate and establish boundaries before engaging in any type of sexual activity.
