For someone that is used to work with imagination and play lots of paper rpg, that's perfectly normal. Whenever i see a female character, even if i know very well that beyound that there's a guy, i feel like having a chat with a nice female. In any case is unlikely that i'm going to meet the guy beyound the computer, and i'm playing with him/her brain, not the body!As in, you met a char, and it's a female toon, and you assigned a 'female' voice to that toon when she talked to you, and then knowing that he is actually a burly guy later, you still hear the female voice. Isn't that just weird? (Not the other player is 'weird', but that you feel weird for switching a 'she' and a 'he' in midsentence when referring to him/her, thinking about him/her. Or when talking about her with some other players). It gets confusing!
In the last we are all part of the same race, the huge differences in the gender come from education.
