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.The idea is presumably to safeguard people from searching for their own spouses on the site - though how a husband would explain to his errant wife how he came to stumble across her picture on a website for adulterers, I don't know.In order to fit in with the general ethos of the website I have invented a wife.She seems rather on edge and sends me a text message at the time we're due to meet asking why I'm using the website.I reply, telling her to come over and ask me face to face. She looks furtively around and asks me if I'm nervous. There is tension in the air like North and South Korea coming together to hammer out a treaty.
But if I'm going to find out what really makes these women tick, I need to leave the safety of the virtual world and see them for myself. I arrange to meet a 41-year-old mother of two who misses "romance and flirting", in a cafe in two days' time.
Our relationship, I note, has suffered because we don't spend enough time together (not surprising really, since she doesn't exist).
After a quick search, I get the measure of the women on the site.
One woman sends me a message heavily laden with sexual innuendo and I come to regard her as the mistress of the single entendre. Another woman's first contact with me included a plan for a day out together, including visits to art galleries, a stroll round a park and then "a few hours under the duvet". I'm later propositioned by someone who tells me she has an hourglass figure.
Her photograph reveals that the hour has stretched to 90 minutes.
Later on I'm perplexed when she sends me two flirty text messages.
