Speaking of sex scenes, I read Philip Roth's The Humbling yesterday. It's short at a very spaced out 138 pages, so good to read in one go.
It's fairly enjoyable, intriguing, darkly comic at times and tautly written -unlike Dickens' David Copperfield, which I was reading before it. It's only the second Roth book I've read, after Portnoy's Complaint, and he isn't shy about graphic sex scenes or language to the point of being lurid or grubby at times - it's a bit odd to think about 76 old authors writing about threesomes with strap-ons, but his writing is so elegant it lifts him above accusations of being a dirty old man I think.
