Who is Better at Writing Sex Scenes - Men or Women?

Martin Amis claims women.

From a short piece on the BBC...

"Once a man is writing a sex scene he's feeling omnipotent... but women don't, and they write better about it," he said.

He also said women write with more sincerity: "There's a bit more song in women's writing, there's more real sincerity in women's writing."
