"Asexual and Proud": The article by Lynn Harris in Salon, which I was interviewed for.
"No Sex? No Problem," an article by Jacqueline Jennings published in The Daily Beast (I am the "Ivy" in the article).
"The Opposite of Sex" in Marie Claire by Lynn Harris. I was interviewed for this; here are Page 1 and Page 2. (I scanned the physical article because I don't think there's one online.)
"Shedding light on asexuality," an article by Lauren Hartog published in Drake Magazine that I interviewed for (though the author incorrectly defines asexuality and makes misleading statements).
Asexuality segment on The Authority Smashing! Hour: David Jay and I had a nice hour-long chat with host Zeno, discussing not only asexuality itself but its relationship to radical society as a movement. You can download an mp3 or listen streaming, or just read the transcript here (it's a Google Doc, transcribed by Sciatrix).
More interviews, articles, and links:
"Glad to be asexual": Article in New Scientist which features several asexual people's perspectives.
"Asexuals Leave the Closet, Find Community": Article in the San Francisco Chronicle which discusses the movement and how a few individuals' lives were affected by it.
"Are There Asexuals Among Us?" The Scientific American writer Jesse Bering writes on "the possibility of a 'fourth' sexual orientation."
"A-Sexomatic: Dealing with asexuality": Article in Elle Canada that discusses the study of asexual people and why it's a legitimate orientation.
"What asexuals reveal about sex": Article by Tracy Clark-Flory in Salon, outlining discussions of intimacy and how asexuality is leading to a broader understanding of how it can be explored in all relationships.
"Asexuals - the fourth sexual orientation": Article by Genevieve Roberts in The Independent, on asexuality being an under-studied population that should be understood as a sexual orientation.
"Prejudice Against 'Group X'": Article by Gordon Hodson, Ph.D., about prejudice against asexuals and documentation that it exists.
"The moment I realised I was asexual": Article by Olivia Gordon in Th Telegraph about several asexual people's experiences and relationships, with a somewhat in-depth discussion of why asexuality is not pathological.
"Asexuality should be recognized as a legitimate asexual orientation": Article by Tracey Hickey in The Pitt News which is well-written and explores the misconceptions many asexual people deal with as well as sharing some perspectives on asexual people who have sex and what kind of non-sexual and non-romantic partnerships can be formed.
"LGBT Soup for a reason": Article by Sophie Cairns in Lesbilicious, examining Ciara McGratten's bigoted perspective that was published in Gay Community News. The original article sarcastically and insensitively dismissed bisexuals, trans* people, and asexuals as not belonging under the gay umbrella, and this article disagrees, offering support and rationale for inclusion.
"The Fourth Sexuality": An old article by Laura, another asexual. (I don't know if the sentiments expressed here still represent her views.)
