So searching around I have discovered there are three completely separate tags in regards to touching ears. There's touching_ears, there's playing_with_another's_ears and there's hand_on_another's_ear.
Is there a way we can just bunch this all together? 3 tags with small groups just because it's a slightly different implied action seems like over-segregation of posts. Maybe have playing_with_another's_ears and hand_on_another's_ear imply touching_ears? Replacing might be the cleanest though. playing_with_another's_ears and hand_on_another's_ear are definitely redundant.
