If the idea is to create some sort of hypothesis about the sex of the artist and the content of the art, I think you'll find a weak link at best. Many artists are influenced heavily by other art that they have seen and admired. Scantily clad or nude women have dominated the history of art. The sex of the artist doesn't change what other art is available as inspiration. I haven't counted up the responses here, but at quick glance, it looks like the numbers of men focusing on women and the number of women focusing on women are about the same.
