Obvious reasons.
Latter tag has some 500 posts.

In some aspects, animal genitalia might be too versatile.

Should it contain all characteristics of animal genitalia such as knot and canine penis?

On hindsight, should there be a human_genitalia tag as well, for fairness? (just for thought)

Okay who's up for having
horsecock -> animal genitalia
canine_penis -> animal genitalia
others???

I could get behind that movement.

That's a different tag with it's own purpose.
I'm sure there are people who aren't into looking animal genitals.
Also, there's a wealth of tags for horsecock that don't have animal_ genitals. Implicate it or remove it. My final 2 cents.

Also that animal genitalia doesn't mean it's the correct genitalia, like horsecock on dogs or vice versa. Or any combination of mis-sized genitals, etc.

I direct you all to forum #44882 for your consideration
