What Girls Want

I'm curious :p Just glancing at profiles I've gone through...I was wondering if the girls would like to elaborate as to what they want in guys on here? And perhaps how do you approach any messages you get :p Like I read somewhere some girls don't even bother with the Flirts, and some read them but don't reply. So yeah? Are the girls on here after nice people? Or just someone they want to screw every so often? I know it would obviously differ from person to person. I just thought if girls could tell us say what they look for and that might help make the system work better. Like I'm not going to spend my money on upgrading my account if it's not going to do nothing as an example :p Ohs and do girls like intelligent guys? Or is that just an automatic "nerd/geek/loser" sort of thing :p Say like if a guy put more effort into their Profile and stuff :p Not just 5 words like "I'm horny and want sex."
