As a female, I would like to politely disagree with your statement about women in general not having to find themselves or having an easier time with anything. Having to find out who you are is what makes being a teenager so full of stress. Nearly everyone goes through it at some point or another.
There are a lot of female furs out there; more than people tend to think. I've seen a whole bunch of artists on FA who are female. Just because you don't see them doesn't mean they aren't there.
Also, the furry fandom itself might not be the cause of having more males than females, but rather the nature of it. It's mainly a subculture born from the internet, and in general there tends to be more guys just using computers on an everyday basis than girls. I've taken enough computer classes to know that there's very often only 1 girl for every 5 guys that are actually interested in being involved in computers beyond the level of knowledge required to check e-mail or Facebook. That ratio is slowly changing over time, but the the world of computers itself is male dominated.
