Right now there's too many men that are females in game, so I usually don't care if im playing with a she or he, so im one of those ppls that would refer to you as whatever gender I might catch from your name, im a man and I play a male character, but from what I have read in these forums and saw in the game im part of the minority.

So in short, don't take it too seriously and a good tip from me when you make a character make the nickname in a way that people can catch easily that you are a woman or man, when im doing a dungeon I rarely check other ppls in my party, unless you have a good piece of gear...
