Ignore the man to the right. He has nothing to do with this post.
While most of the stuff I sell on eBay is gay male porn, I do, on occasion, sell some non-male stuff - like this lovely book: Up Hers.
From the introduction: "Up Hers is one of the frankest and most detailed descriptions of the most vicious perversions of them all - sodomy and lesbianism. Although the subject matter of this novel is unusually sensationial, the reader should be advised that this perverse abnormality is, along with many other unusual deviations, far more common than he might imagine."
For those of you who are not eBay members, but you're curious what naked ladies look like, here's a peek from this 1970 Neptune Reader book.
