After a quick search, I get the measure of the women on the site."My preference is for a man who is much younger than me with rugged features," says one. This is a way of paying someone a compliment without typing out the words. And over the course of a week I get almost 100 replies, messages and propositions.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." What a masterpiece of understatement.
And all of them are looking for an opportunity to betray their spouses. But I wanted to find out what sort of woman uses such a site.
"I want a man with a personality and looks to take my breath away." These are the requirements of the dark-haired, dark-eyed, 37-year-old Asian beauty who has sent me her romantic wish list.
Reading it on my laptop in the aptly named Cafe Affaire in central London, I consider what she really wants: a no-strings-attached sexual relationship.
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.
