Is it true that most american college girls are easy?

is it true that most american college girls are easy? I've heard that most American girls in college have no morals and would do anything for fun. They apparently tend to be very loose...Is this true? Someone also told me that they tend to be very artificial and everything is about looks (abs, etc) since they probably don't have the intellect to look beyond just looks...Is that true or is the guy that told me this an idiot? Thanks
