Implicating tail_masturbation → tailplay

Nothing against the implication only the tag itself, it's just same issue as with tail_penetration i.e. sounds a little like you're masturbating your tail and not masturbating using your tail (I believe we have one or two images depicting that on the site, but couldn't find them).

Ah, my bad, I meant we have one or two posts depicting "masturbation" of the tail (seen at least one but I never figured what to tag it with, hence I can't find it).
