Whether we speak personally or Palaeo-anthropologically, it's fair to say we humans start out fiddling with ourselves. Our improved scan  technology reveals that most of us commence a life of self-pollution while in utero, while if we trace our culture back to the first artefacts that showed we had a culture, then we find ourselves confronted by a hubcap-headed humming-top of tits and ass carved lovingly from limestone, excavated from an Aurignacian settlement discovered in a North-East Austrian village known as Willendorf.The mighty Robert Crumb, back in his awesomely prolific Weirdo days, depicted the creator of the first Venus of  Willendorf as Caveman Bob, a neurasthenic outcast with a strong resemblance to Crumb himself, perpetually horny, crouching in his cave and whacking off over the big-butt fetish woman he'd just made: Homo erectus.Crumb's point, in all probability, was that while she may well have functioned as a magic icon to induce fertility, and while to modern eyes she stands as an example of the prehistoric genesis of art, Willendorf Venus was an object of arousal in the eyes of her creator, was a piece of stone-age stroke  material, primal pornography. He may also have been saying that if we trace culture to its very origins, we find its instigator to be an obsessive smut-hound and compulsive masturbator much like Crumb himself, or me, or you, or any of us if we are to be entirely candid.
