"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.

Reading it on my laptop in the aptly named Cafe Affaire in central London, I consider what she really wants: a no-strings-attached sexual relationship.

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.

Whether you’re 13, 14, 15, 16, 17, 18, or 19, these sites will put you in front of the right crowd and won’t use up all of your food and going out money!

Match is strictly for teens aged 18 and 19 (as well as young adults, millennials, and seniors, among others).

Once you verify your age and email, you can finish filling out your profile, specify what you’re looking for in a friend, date, or partner, browse through members, receive matches, and send virtual winks and likes.

Founded in 1995, Match is the leading dating site no matter what your age is, and it’s led to more first dates, second dates, relationships, and marriages than any other.

After a quick search, I get the measure of the women on the site.

"My preference is for a man who is much younger than me with rugged features," says one. This is a way of paying someone a compliment without typing out the words. And over the course of a week I get almost 100 replies, messages and propositions.

Your picture can be viewed only if you give a password to the person with whom you are conversing.

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.

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.
