Do I see it right, that this tag is very often wrong used?
-Tentacles are no character, in most cases. So they shouldn't be tagged with a gender, right?
-Disembodied_penises are always male characters.
-Characters with visible genitalia should be identifiable in most cases.
-Fingering and fisting shouldn't be tagged as penetration, therefore no ambiguous_penetrating
The only exception I see at the moment are tentacle monsters or similar with obscured genitalia.
