The original penulis of sailor moon had the Three Lights girls crossdressing as guys, but the anime was different. In the anime, the Starlights were girls on their planets, but took the form of guys on Earth. Their true form is female, yes, but there is a male disguise. Complicated, isn't it?
In the manga, they were girls who dressed as guys. In the anime, they were boys in their civilian identities, but turned into girls when they transformed in their senshi identities.
