Any experts in grammar/english/plurals here?

It can be either penises or penes.

Oh no, here we go, it can't. It is archaic, because the word has been
absorbed into English. It's etymology is latin but the word no longer is,
thus its plural follows the rules of English.

Unless you read Wikipaedia which is a dreadful mistake :-)
