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.
 

An article came out recently about a study, which looks like it was conducted on the pacific rim because it rather oddly specifically mentions asian women, which is "complaining" that while gay men are using condoms more for anal sex (or claiming to), that straight women are having more anal sex but not using condoms.

As a followup on this study, queerty published an article entitled "Why Lesbians Should Teach Straight Women About Anal Sex" in which it is claimed that lesbian women have a better record of practicing safe anal sex than straight women.

This seems likely lol. But still it's a new article about anal sex therefore worth a link click and a quick read, if only for the silly pic illustrating what anal lesbians might look like – like anal burses in shiny latexy nurse costumes apparently. Somehow I doubt a real lesbian chose the pic.

Psychology today isn't usually a great source of info on anal sex – I've seen several anti-anal articles posted there. But recently they covered the topic of rimmimg, ahhh, that's rimming, in a way that has the usually psychtoday fastidiousness and fear of shit, but is still worth a scan.

At least they mention Jack Morin, one of the crop of reputable experts on anal sex. His book, Anal Pleasure and Health, should be on the anal students reading list.

Here's a snippet from the article.

Analingus feels erotic for the same reason that anal play in general feels arousing. The anus and surrounding tissue are richly endowed with nerves highly sensitive to erotic touch.

In addition, lovemaking draws much of its emotional power from intimacy, lovers' deep acceptance of each other. Analingus is a way for the rimmer to say: "I love all of you. No part of you turns me off." It's a way for the rimmee to say: "I'm totally yours. No part of me is off limits to you." Such mutual acceptance can be a powerful turn-on.

Of course, rimming also involves a big fear, fecal contact. Not to worry, says sex therapist Jack Morin, Ph.D., author of Anal Pleasure and Health. Soap and water remove any traces of stool, a good reason to shower together before trying analingus. For extra safety, the rimmee might also use an enema or two before washing.
