Goodboygender describes those who experience gender expression in an animal-like way. It is under the kingender umbrella, as it correlates with one's kintype, influencing the way they perceive their gender. It is not a masculine/feminine/androgynous gender, as it is gender experienced in an animal-like way.
Despite the name, goodboygender is not limited to those who are dogkin. Goodboygender is open to all Otherkin kintypes.
A good, easy explanation of goodboygender is that it involves gendered terms in the way a dog experiences them. For example, 'he/him' but in the way one calls a dog he/him without knowing its gender. Or 'boy' but in the way someone calls any dog a good boy, regardless of gender. Connected to the usually joking saying that all dogs are boys.
