NOTE: This is a repost of a piece I originally posted on Pillowfort,
here.

If you've spent any time in the asexual community, you'll probably be aware that cake references and food analogies are very common. Recently I discovered a cake analogy printed in a publication for a similar community, the celibate community of the 1980s. The quote above is taken from a book titled The New Celibacy by Gabrielle Brown, Ph.D, as printed in The Celibate Woman Journal volume 1, issue 1, July 1982. The Celibate Woman Journal was aimed at an audience of women whose community emerged from the 70s lesbian feminist community, and the journal was often advertised and discussed in lesbian newsletters/magazines/newspapers of the time.
While this analogy wasn't made by an asexual person, this community seemed to be aware of asexuality as something separate from celibacy, as you can see in this quote by another person interviewed for The New Celibacy:

Note that she says she's "very sexual" and "not at all asexual", but has been celibate for a year for her own reasons. Given that she identifies as celibate, she can't be using "asexual" to refer to a lack of sexual activity on her part, since she says she isn't asexual. Asexuality is clearly understood to be something else.
If you've enjoyed this snippet of commentary, keep an eye out for the book I'm writing, titled Rewriting Asexual History. This is just one source out of hundreds I will be discussing. I plan to release the ebook for free download.
