I register, and enter the murky world of two-timing technology, taking note of the warning on the site: "Not all affairs have a positive effect on a marriage."

"I'm witty, charming, handsome and modest, and I'm kind to animals," I write, hoping this description will have a fairly broad appeal, and also include a recent photograph.Reading between the lines, I suspect she wants to meet again.Sadly, I feel I have got all I want out of our brief relationship - two cups of coffee and a short conversation - and it's time to move on and find someone new.After discussing how mundane marriages become and avoiding questions about my personal life, it's clear we're past our sell-by date after ten minutes, never mind ten years.

She has declined to tell me her name, so I have to think of her as her web sobriquet.
Her photograph reveals that the hour has stretched to 90 minutes.
I'm already starting to feel like I've had enough of this experiment.
