If you look at the slick and glossy high-end women's fashion magazines, the first 70 pages, or more, are advertisements for very expensive merchandise ... many, if not most of those advertisements will be based around very artistically shot pics of naked, or nearly naked, women shot by the most famous photographers in the world ... The publishing and fashion industries aren't spending millions and millions of dollars a year on a "myth"!
The demographic research and sales analysis proves that almost all women are in some way, and to some degree, attracted to other women. Vogue, Elle, Harper's, and the others would have been out of business a long time ago if that weren't true.
