I use "He" by default. I swap to "she" if I'm asked to do so.
And I'm not even thinking that when I say "He" is a male or when I'm say "She" is a female. I don't care at all. I'm just taking the option more probable.
Seeing this

Quick googlesearch talks about 60-40% split acording to BBC, but I think that they problably asked in game or something like that,acording to my experience is not true. I woud say 80%-20%
But anyway, this shoudn't be a big deal. No one shoud treat you diferently for being one gender or another, so what? If you feel insulted for an asumption based on a fact (most female characters are guys in R.L.) the problem is you actitude. I undertand that you can feel bad about it and you have a real life problem about it. But you have to take in mind that no one wants to insult you with this.You are the one who have to overcome that feeling.
