In order to fit in with the general ethos of the website I have invented a wife.
Our relationship, I note, has suffered because we don't spend enough time together (not surprising really, since she doesn't exist).
It may sound like an unpleasant niche website for a handful of amoral people to whom wedding vows never meant very much.
I feel sorry for her husband, presumably unaware that the mother of his children is pursuing cheap thrills with strangers.
By now, I have been contacted by scores of women, so I arrange dates with the ones who are prepared to meet me in the next few days. Blonde, slim and relaxed, she has already told me by email that she's been married for ten years, has young children, time on her hands and wants to add a frisson of excitement to her life.
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.
I wonder if anyone has ever read this, seen the wisdom of it and decided not to join. "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.
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 doesn't want to discuss her husband, and I feel uneasy talking to her.
Despite this, she still seems keen to flirt with me.
In the end, we agree to part and she wishes me luck and assures me I'll find the perfect paramour. This was like having a meeting with a new accountant with a helping of self-disgust thrown in.
Later on I'm perplexed when she sends me two flirty text messages.
Many of them are middle-class, many have young children.
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.
So I paid £119 for a month's membership, giving me an entre to thousands of faithless females.
