Woman-to-woman kiss: [OK].
"Sodomy" is taboo. "Lesbianism," on the other hand, is a male-coveted bourgeois perversion. There's a long history of patriarchal flirtation with sapphic themes in literature and art. Baudelaire's lesbian poems in Fleurs du Mal, Gautier Mademoiselle de Maupin, and Balzac The Girl with the Golden Eyes (amongst many others) use lesbian sexuality as a field in which to play out male confusion with prescribed roles for men and women. Through lesbian personae, late-Nineteenth Century men cross-over into the forbidden territory of feminine feeling and bodily sensations. No doubt, but there is a limit.

Man's fin de siècle heterocentric representations of lesbian sexuality are surprisingly flat and one-dimensional. They privilege the stereotype of the "passive" lesbian, which poses little threat to patriarchal mastery of desire.* Yet, inevitably, man's playing on with lesbianism brings forth the possibility of softer, lenient man-to-man ideations.**
The system will not tolerate any subversion of patriarchal power.
