Of course it doesn't work :P Women think I'm a creep and to be honest I am, there's not much I can do to change myself. If I find someone attractive I go straight for a relationship, not friends. I don't want to be 'friendzoned', as they say.
In my experience women can very rarely initiate contact in that manner, social expectations are for the man to do all the hard work in the beginning. There are plenty of horny men, women just have to wait and filter out the ones they don't want.
My experience is pitiful though, high school and hitting on women over the internet.
