First, the milking tag is being used to cover breast milking as well as penis milking. As of right now, milking has no wiki, but I feel like it should either be used exclusively for the actual action of extracting milk from a character, or else as an umbrella for extracting any liquidy something from wherever on a character.

Then there's semen_extraction. It's only got 11 images, so we can just retag those images, but I wanted to throw it up for discussion, in case anyone wants to alias penis_milking to semen_extraction. If the consensus is that it should be penis_milking, I see no need for an alias, and a quick tag cleanup will suffice.

Thoughts? My personal vote is that milking is clarified to mean pump extraction of milk (or something) from a character's tits, while penis_milking really ought to be aliased to semen_extraction.
