How do women who develop a shell to repel the casual advances of men go about dating and meeting guys?

it isn't the woman just being b*tch....she can spot the type of guy who just wants her for her body/looks. If a guy doesn't even know you approaches you then the only feelings he has for you are between his legs!! women don't want horny dogs we want gentlemen and kind men who want to get to know us before making a move
