No sign up only sex chat
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.
Dance clubs and dive bars may have worked in the '90s, but now, even if you’re out, your phone is a much easier way to find someone to "watch Netflix and chill" with (especially someone you won’t regret tomorrow).
And the great thing is, whether you prefer chatting extensively with your new crush first or a little fantasy in your play, there are diverse options to suit your every whim and desire.
So I paid £119 for a month's membership, giving me an entre to thousands of faithless females.
They are allowed to sign up for free as a way of ensuring the numbers are balanced between the sexes.
"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.
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 the end, we agree to part and she wishes me luck and assures me I'll find the perfect paramour. This was like having a meeting with a new accountant with a helping of self-disgust thrown in.
Later on I'm perplexed when she sends me two flirty text messages.
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.After discussing how mundane marriages become and avoiding questions about my personal life, it's clear we're past our sell-by date after ten minutes, never mind ten years. She doesn't want to discuss her husband, and I feel uneasy talking to her.
