Eikichi was the only character I could remember that fits that description going by appearance (he's pretty flamboyant), but he wasn't actually gay. He dressed like someone out a visual kei rock band and the only love interest he had in the story was a female character.
You, the main character, could engage in a homosexual relationship with a male character, which is probably the other real reason.
