Not really. I'm just as feminine in real life as I am in gaming. I don't think I've ever played an MMO where someone wasn't completely shocked to find out that I'm actually a man. Similarly, I've encountered soo many people who were completely shocked to find out that I'm actually straight.
I'm as open in games as I am irl, whereas I treat everybody I meet as if they're somehow close to me and I'll tell them anything

.
To my own dismay, I spend most of my gaming time helping others and, also to my dismay, I've thrown away several goals to help others irl.
On top of all that, I'm as irritable and stubborn in games as I am irl lol. There are soo many little things that can piss me off, and I will hold a grudge like no other for... at least an hour.
