[Joke] "Do you know what I want?"

A certain guy had never had sex in his life, so his friend told him that he'd take him to a girl that 

would teach him a few things. He agrees. 

Later that week, he's in a room with the girl. She takes off her clothes, and asks him, "Do you know what I want?" 

He says, quite honestly, "No.". She lies down on the bed, and asks him the same question again. 

Again, he answers "No." 

Now, she's not sure exactly what to do, so she spreads her legs all the way; we're talking spread-eagle. 

She asks, "Now do you know what I want?" 

He answers, "Yeah. You want the whole bed to yourself."
