Only a few I could think of. And most of them I've heard or know they've played something at some point, not that they especially like video games.
In PC multiplayer gaming, especially in CS:S, girls aren't treated any differently than boys. No one makes a fuss if there's a girl on the mic, as far as I've noticed. I do remember one odd time though, when some girl was talking some nonsense, ranting on the mic and the others were playing and minding their business rather than talking back to her. You couldn't hear steps or anything and her stories weren't all that interesting.
Someone said "shut up for a while" in the midst of a round in a neutral manner and after that she just started raging and yelling about she can say anything she likes and you're just picking on me because I'm a girl and stuff like that. I thought it was hilarious as no one gets agitated so easily. Soon she became very annoying and when during and after the raging no one was interested in her in other ways than trying to shut her up or agitate a bit more to see what would follow, she ragequit.
It was clear from the beginning that she was just desperately seeking for attention and wanted to be treated in a special manner because she was a girl, rather than just playing the game and getting the same treatment like any other player there. Gender had barely nothing to do with that story though, just something that crossed my mind.
