Oh good trick, you titled it "female slave" so that more people will read your post.
Do you really think that will help you find an actual female? You do realize that everyone who reads this will be guys like you, right?
4 to 1 is not a good mix. And anyway that's probably the numbers on the site as a whole. I'm thinking girls are less inclined to participate as single individuals than males, meaning the 'personals' section will have a higher ratio.
Is it greater than, less than, or equal to 10:1?
I mean seriously it seems like every female gets about 25 requests, every guy gets one if he's lucky. What's the point? I feel like I'd have better luck as a pop up ad.
