First of all, when you get to the first screen you have the option to click on either "about us", "game" or "F*CK ME" (would THAT be where they've hidden their "safe" sex info? No wonder it's so popular.)
Then you can choose to be male or female and you decide if you would like to have sex with a male or a female. And if you're REALLY lucky maybe you'll find one of those nice Viagra pills. Of course, you must avoid the Nun...
