Why "leaving"? I don't think there were any more than that ever.
And those dominant women are most likely lesbians too :)

I think those numbers are actually even pretty good, as I expected situation to be even worse. Women have very very little interest in sex and it seems to be pretty normal ratio between men and women in any sexual topic. The same will be on any dating site or club.

However if we look on self harm community or any other attention whoring unrelated to sex, you will see like 90-95% women there.
