The tag alias #77655 licking_own_pussy -> autocunnilingus has been approved.

Reason: "A form of masturbation where a character's mouth or tongue is used to stimulate their own pussy and clitoris."

Not 100% sure if this should be an alias or an implication, but either way it seems necessary

This makes sense to me. The total tag count history is low, but there are other adjective_own_noun tag schemas, so users may think it applies here too:

Piggybacking off of the alias, I would recommend aliasing licking_own_vulva and licking_own_vagina to autocunnilingus as well. Yes, I know vagina is more nebulous and not quite the same, but the autocunnilingus tag already lumps together a character licking their own vulva and clitoris, so these should be safe to include. That can be done in a separate BUR if there's no friction with approving this one.
