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.
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.
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.
