Like many other shoujo anime BSSM has a fair share of gender bending and homosexuality in it. This type of stuff is not uncommon in Japanese anime. Japanese culture is different from Western culture and people don't have a problem with that sort of thing

Fisheye
The cross-dressing member of the Dead Moon Circus is one of the more prominent homosexual characters in BSSM. All of his victims were men and in one episode he kisses Mamoru. He always approaches his victims dressed as a female. In America Fisheye was changed to a female character

Kunzite and Zoicite
These two Dark Kingdom generals shared a anime-only relationship. In America Zoicite was changed to a woman to prevent any homosexuality. In one episode Zoicite dresses as Sailormoon. Of course in the American version this presents no problem because Zoicite was female

Haruka and Michiru
The famous couple never share any kisses in the anime or manga but there it lots of implied dialogue that lets you know they are a couple. In America they were made into cousins with most of their dialogue and hand-holding scenes were editted

The Starlights
The Starlights are female senshi who pose as men on Earth. In the anime they took men bodies in the manga they only dressed as men. They have not been dubbed in America yet
