Anyone really want to take sex advice from, say, Bertrand Russell? Hegel? Plato? Nietzsche? Heidegger maybe - at least when he rutted it was with Hannah Arendt. But you get the idea.
If I wanted sex advice from someone in an intellectual field it'd have to be Johann Sebastian Bach. At least he knew what the heck he was doing.
Heidegger did Arendt? Sheesh, just imagine the conversation over cigarettes afterwards....
