Kenneth Grant enthusiastically endorsed the consumption of "vitality globules" daily to improve health and build magical power.
If I recall correctly, he also referred to semen as the "menstruum" of the New Aeon.
Generally, sexual fluids, particularly in the mixed form of an elixir, have multiple applications, though when spoken of openly suggest recipes for monstrosity of the kinky sort. Grant uses the conceptions of "kalas", which apply initially to female secretions but can also be found in the male - 16 types reflecting in each, to form the 32 paths.
Not many folks can grasp the artworks of HR Geiger any more than they can grasp the hypostases proceeding from the Ain Soph - but the "light shineth through", so to speak.
The Male is Fire, the Woman is Light, and yet each contain the essence of the other. In the former you have the essence of the stars, while in the latter you have the magnetic links that bind all things and direct their courses - both applying to generation and corruption.
