Over your impotence
[Emily Dickinson, #854, c.1864]
literary or artistic works having an erotic theme; especially, books treating of sexual love in a sensuous or voluptuous manner.

It is usually distinguished from pornography, which can also have literary merit but which is usually understood to have sexual arousal as its main purpose.
