This article about anal sex 101 is fairly sparse on the actual 101 part (and the anal sex part), but it might be of interest.
I liked her "what makes for good sex" paragraph – talking, lube, and laughter, thats damn good advice – for some people at least. Not everyone approaches anal sex the same way, and not every girl wants talking and laughter (use the lube tho).

In the anal class, everyone will write down myths they've heard. I'll talk about what a butt plug is, what anal beads are, and why lubricant is so important. I'll pass around different lubricants and talk about why they're good or not.
What makes for good sex?
I have three rules. One, communication is key. If you can't talk to the person you're having sex with, why are you having sex with them? The second thing I say is, "Lube is Love." And third, laughter. Sex is so awkward, and people make funny sounds and weird faces, and crazy things happen — like a dildo gets thrown across the room, or the kids walk in. You've got to be able to laugh. Plus, laughter releases endorphins, which makes the sex feel even better.
