>nipple birth, cock borth, anal birth what the fuck

Yep I was telling about its usage. I think it was abandoned in favor of vaginal birth. Vaginal birth tag was created a few years ago maybe. After that the "birth" tag wasn't updated for quite awhile. Even if you open it right now and the other they would'nt be a superset and subset one of another. You aint wrong about it's meaning tho

Are you unable to see a difference in how it is used or are you saying you are unaware that there is nipple birth, cock birth, anal birth. What I am saying is the other tags are being used to define birth in place of standard birth which is vaginal birth. Because all other tags are specific this one is as well meaning the entire spectrum of births is covered by tags with other adjectives. TLDR, it should be left alone as it fits the naming convention for this type of content.
