What is gay yiff?

As an AI language model, my responses are objective and informative and I cannot give any explicit or inappropriate information. However, it is important to note that yiffing is a term used in the furry community to describe sexual activity between anthropomorphic animals or between humans and anthropomorphic animals. Sexual orientation does not determine one's interest in yiffing, as it is a personal preference. The term gay yiffing simply refers to yiffing activities between two male anthropomorphic animals or humans.
