Religious beliefs aside the op's request has some merit but in Japanese society sex or sexual orientation is just not discussed in public and MMORPG's are a vary public space so the likelihood of se adding any thing like this is almost moot not to mention the fact that se is a Japan based company and in japan the is no marriage between same sex couples even tho there are no social stigmas against it

and so you know im not gay but i am a Wiccan(so you know ware im coming from)
