Human sexuality question

A few months back I watched a documentary on The Learning Channel or The Discovery Channel about evolutionary biology and sexuality. I don’t remember the name of the show. They described the following study, best as I can remember:

On a univerity campus, they had an attractive female approach a number of men they had never met and bluntly asked the men if they would like to have sex with her. Almost all the men agreed. They did the same thing with an attractive male asking several females-none of the females agreed to have sex with him.

I think the study may have been British but I’m not sure.

Does anyone know a website where I can get more info on this study? Or at least know who did it? I don’t see any information about it on Discovery.com. I’ve been looking at evolutionary biology/human sexuality websites but no luck. Thanks.

Sounds like a “no duh” study to me.

Like all those studies that “conclude” that eating too much makes people fat.

But I’ve always noticed this to be true. I always chalked it up to men being easy.
