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.
She has declined to tell me her name, so I have to think of her as her web sobriquet.
"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.
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).
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.
What I don't know is how her husband will feel about it. Aside from the little matter of her marital status, she also believes I have a wife, but she doesn't care.
She wants instant gratification even though we've exchanged only a few words online.This is how I find myself waiting for "Sophia Loren".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.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.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.
