But in the modern world, in which the internet has become a vehicle for all manner of impropriety, she regards this kind of behaviour as perfectly acceptable.
Suddenly the realisation of how odd it is to meet a stranger with the express intention of having an affair dawns on me. It's more like Alan Sugar interviewing an apprentice.
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.
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.
