A new social experiment from a group called "Whatever" shows that men are twice as likely to turn down sex with random, attractive women. In a new YouTube video, the group hired an actress to ask 14 random guys for casual sex – and half the men turned her down. One man even called the cops on her.

Turns out, another group performed the same experiment 25 years ago. At that time 75 percent of men consented to sex with a stranger, proving that today’s men are more cautious than the men of the past.
