The problem with trying to outlaw something is you just end up increasing demand. Ask D. H. Lawrence, the author of Spycatcher or anyone who's ever tried to ban Judy Blume's Forever from a girls' comprehensive. You also end up giving the thing an air of saucy mysteriousness it almost certainly doesn't deserve. Spycatcher is basically about working in the civil service. Forever is about a boy who calls his penis Ralph. Lady Chatterley's Lover is all billowing flanks and primordial tenderness, which is nothing compared to what you can watch women doing with lengths of rubber tubing on the internet these days.
