Zantetsuken, I think there is a third category of people who want to marry their partners in-game but don't play their actual gender. There have been several replies to this effect. It's a smaller group, but, it's becoming increasingly common to see couples play MMO's and to see men playing female avatars and vice versa

(Aside, It may be worth pointing out that in one of Square Enix's own videos, they shown a male hume being played by a woman (at least... it really sounds like a woman!) and a lalafell female being played by a man. http://www.youtube.com/watch?feature...&v=n-vjy97RuoA )
