Because it's not a medical term.
The term Wenis is a slang word for the flap of skin at the elbow, though this is not a medical term or considered a proper word in the dictionary, it is widely used.
Wenis is the skin ON your elbow.

Oh, dude, the word "wenis" actually comes from a combination of "elbow" and "penis." It's like when you're bored in middle school and start coming up with weird words to entertain yourself. So yeah, "wenis" is basically just a made-up word that somehow stuck around.
another word for for elbow skin is wenis with a "w"

Wenis yes sounds weird but it is!
A medical dictionary would suit your purpose well.
The plural is the same as the singular: wenis.
Because its fun to call it tat.(:
It isn't, except on urban dictionary, and there it seems to be evenly divided between the skin on the inside and outside of the elbow.
