I got girl friends that prefer to marry another girl cuz they are single and single guys want cyber or just start to flirt when they don't want to (no all the guys of course, but there's a good number that they do). I saw this happening with a lot of girl friends. I even knew some of the guys and introduce them to my other friends and warm them, but they didn't listen cuz ...omg a girl was there. I would totally marry any girl (check my app), whether not she plays as a woman in game. It doesn't matter to me. I just want another girl with similar schedule to mine to play the in-game content.
Another thing a heard ia that some servers just have mostly married couple or couple (gf/bf)from RL so it is probably mostly the server you play in. Keep looking.
