If you're one of those guys who needs a chart to do anything useful, here's the one to get printed on a poster and tape to your ceiling: a venn diagram of how to talk during sex. Good: "Oh God!" Bad: "We're going to hell for this." Good: "ROAR!" Bad: "SOOOWEEEE!". The bad "Thanks" string at the top is awesome, too. Better yet, just read the bad side: for one, it helps more to know what not to say; better yet, find a girl who is turned on by that side of the chart, and you better fucking hold on to that woman forever, you'll never have crazy-ass sex like that ever again.
