-- No, we need tits and arse because they have got to be available to us; to be pawed, fucked, wanked over. Because we're men? No. Because we're consumers. Because those are the things we like, things we intrinsically feel or have been conned into believing will give us value, release, satisfaction.

We value them so we need to at least have the illusion of their availability. For tits and arse read coke, crisps, speedboats, cars, houses, computers, designer labels, replica shirts. That's why advertising and pornography are similar; they sell the illusion of availability and the non-consequence of consumption.
