But it claims to have more than 100,000 members in the UK.
Many of them are middle-class, many have young children.
We have encountered one another via an internet dating service established for the sole purpose of enabling married people to commit adultery.
It may sound like an unpleasant niche website for a handful of amoral people to whom wedding vows never meant very much.
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.
But she is an old hand at this type of encounter and tells me she's met many men through the site, and that I was probably the only one who hadn't lied about my age.
These days, lots of dating apps pull your information from Facebook, allow you to add some additional stats, and get started on swiping and messaging from there, which means that the social media juggernaut is practically a requirement for online dating.
But whether you're ready to delete your account or you never had one in the first place, there are plenty of dating apps that work without Facebook.
Some prefer not to have a Facebook at all (myself included), while others have a profile, but would rather not drag mutual friends into the dating equation.
Whatever the case may be, there are enough dating apps in the sea to satisfy pretty much every possible need.
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.
"Sophia" tells me she thinks relationships have a shelf life of about ten years before boredom sets in, but that she stays married to ensure her children have a stable home.
