Definitely double standard by Tim. The words *glass* and *houses* and *stones* come to mind. Not to mention *kettle* and *black*.
Tim has the exact personality of someone who would think it was ok for a bloke to have sex with someone based purely on fancying each other and nothing more, but it's not ok for women. The same girl that he slept with one time because he only liked her looks will be the same girl he'll slag off for being *easy*.
Doesn't seem fair, but people like Tim are a law unto themselves anyway.
