Insights into seduction which Kundera doesn't usually dare include in his novels. The story of the Hitchhiker, for example is just dark. In other short stories he makes the lotharios into buffoons. Perhaps unsurprisingly, Kundera also glosses over one Casanova's insights into romance and women.
It's not likely Kundera is any kind of feminist, which may or may not have made him popular with ladies in the old Czechoslovakia, but as an honest portrayal of the humbling slapdash humour which Kundera probably grew up with, in Brno, Prague or wherever, it's priceless.
