ImportantNobody said If you expect me to be a macho man I'll certainly let you down. I wonder if it's low testosterone or what, although I'm not worried or wish I was different.
Don't try to rationalize it with biochemistry, you are who you are.
Edit: Also on the "gaming is mostly a guy thing", not only is that stereotype getting increasingly false, it pretty much already is completely false. Roughly 47% of gamers are female. I suspect though that a majority of them don't advertise their gender because the gaming community is incredibly hostile to women for some reason.
