With the recent "cub" changes marking a well needed trend toward more descriptive language in tags, I think it's time we re-examine the language surrounding female anatomy.
Currently, we tag penises as 'penis' and vulvae as 'pussy.' Ignoring the claim that this has potentially sexist implications, I think there is still merit for the change. For one, 'vulva' is a specific term for that part of the body, while 'pussy' is a slang term that can colloquially refer to a number of things, such as the vaginal canal, the womb, the uterus, or the vulva (or more commonly, all at once). However, we use the tag 'pussy' to describe just the vulva and the vaginal opening. Secondly, the current tags related to the pussy tag are wildly inconsistent. We have both 'pussy_ring' and 'labia_ring,' for which the difference is unclear, and we have 'vaginal_masturbation' which seems clear, until you compare it to tags like 'vaginal_penetration,' 'clitoral_masturbation,' 'penile_masturbation' or 'tail in pussy.'
Furthermore, the only justification I've found on this forum relating to why we tag this way is "Because most people don't know what a vulva is," which, not only IS sexist; it is holding our user base to a degree of intelligence that is quite literally lower than a fifth grader.
