I'm back. I decided last year that I wouldn't continue this effort, but here I am again. However, I will no longer maintain a web site with a collection of links to and quotes from medical sources ("The medical aspects of anal sex"). So, if anyone would like that to be updated one last time and uploaded somewhere, let me know via PM. I'll put that back into my signature, if FreeOnes allows linking to the upload site (RS is right out).
It seems that the mainstream media is
finally reporting on the rise in the popularity of anal sex: "
Study Reports Anal Sex on Rise Among Teens" (ABCNews, Dec. 10, 2008).
Recently, researchers at the Bradley Hasbro Children's Research Center in Rhode Island suggested that anal sex is on the rise among teens and young adults, particularly those who have unprotected vaginal sex.
...
[Megan] Carpentier said the dismantling of comprehensive sex education programs in the public schools is to blame for teen ignorance about the hazards of anal sex. And it is unrealistic to expect doctors to talk to teens about this touchy topic.
...
According to the Journal of Adolescent Health, rising rates of anal sex among teens is reflected in the general adult population where anal sex rates have doubled since 1995.
Unfortunately, the reliance on advice from people with no medical backgrounds continues...
"It really is shocking how many myths young people have about anal sex," said Judy Kuriansky, a Columbia University professor and author of "Sexuality Education: Past Present and Future."
...
Columbia's Kuriansky, author of "Generation Sex," has been hearing questions about anal sex from her college students for at least a decade...
Here's her
biography @ SexualTherapy.com. It brings to mind the background of another non-medical "authority" on anal sex, Jack Morin (
biography @ HarperCollins.com), who wrote a book about it and is still quoted in
Wikipedia's article about it regarding incontinence: `[Dr. Morin] had never personally observed "loosening" in any of his patients.' (Why would a
psychotherapist observe that in his patients? Did they go to him for their proctological exams?

)
And, of course, there's Tristan Taormino, another "authority" with ... wait for it ... no medical background (Shocking, eh?
Her biography at IMDB):
One speaker on the college circuit -- Tristan Taormino, author of "The Ultimate Guide to Anal Sex for Women" -- is gaining new ground with young women.
