Men spend their free time thinking about sex
Woman spend their free time focusing on their appearance and men
Men are each different, individually, and so are women. I was married to a man who liked to spend most of his free time fixing computers for other people. I know a man now who enjoys talking incessantly to his friends and neighbors, and likes to shop. Over the years, as a woman, I have spent my free time doing all sorts of different things...so I don't think you can generalize too much.
Do you seriously expect us to generalize that much? Not taking into account say, age, wealth, working hours, relationship status...and the very long list goes on.
These days staring at random websites and waiting for someone to log onto skype to talk to.
Maybe turn on a video game if I'm in the mood. Rarely am.
