“The main issue with Tinder is that, as its popularity grew, so did its functionality,” one 27-year-old Fab Swingers user tells me. “It went from being ‘the booty call on campus’ to a universal dating app.”

He also believes that traditional swinging has dwindled because of generational change: “Swinging isn’t as popular with younger demographics due to poly couples becoming more commonplace. “

Most recently, he says, he’s seen a huge rise in young women joining Fab Swingers because of what he calls “the normalization of ‘daddy’ kinks.”

He says that, since Craigslist deleted its personals section last March, users have scattered not only to Fab Swingers but also FetLife and Reddit

At 4 AM, a couple in their late-30s asks, “Who’s around now SE9 for a 3 sum [sic]?” before giving out their Kik username-an anonymous messenger app used by many Fab Swingers members.

Breeding is a common kink among dominant men on Fab Swingers, says the 23-year-old woman I speak to” “I get a lot of guys enquiring about it, and even offering to pay me to cum in my pussy

One downside is fakes. Despite most users being verified-if not by others, then by photographing themselves alongside their usernames-thousands are not. If a profile has no verifications and isn’t brand new, something is likely afoot-especially when photos of a beautiful woman or impossibly large dick are involved. These fakes often invite unsuspecting users onto Kik, where they’ll solicit face pics or videos before disappearing, having presumably gotten their kicks.

Though Fab Swingers claims to safeguard against this, Google image-searching someone’s photos before chatting is smart, as pictures are frequently taken from porn sites and social media.

Another downside is the prevalence of unprotected sex, as evidenced not only by photos, but profiles where interests like “bareback” and “cream pies” are explicitly stated. The sharp tip of this iceberg is “breeding,” a growing fetish where people literally aim to conceive a child during no-strings-attached hookups.

In fact, I’ve been getting close to a new dom who’s very into the idea of breeding me. To him, the best way to make me his is to plant his seed in me. It’s about ownership and intimacy for some.”

The 27-year-old guy I speak to, however, believes that Fab Swingers’ biggest downside is the lack of inclusion. “Fab offers people the opportunity to indulge in certain desires-however, it also highlights questionable personal values and cultural views,” he says. “I’m bisexual. Some members from older generations or religious backgrounds refuse to associate or message someone labeled as such. Apparently, hosting an orgy is fine, but the fact that you e sex is immoral.”

Trans people get it even worse, he says: “The aggressive views people have toward [them] are far more openly hostile. Even having your profile verified by or linked to a trans person is a black spot to some.”

It’s 7 AM now and the sun is rising on another cold Sunday in London. A guy with “creampie” in his username has evidently had a great evening, writing, “Wow what a night, another non-stop cum filling gangbang party with 2 girls going home dripping with warm cum.”

When users meet, some prefer to have a drink first, while others like getting straight into it, with reviews dripping with tales of women opening doors in lingerie. Generally, women and couples seem more open to accommodating, while men seem more open to paying for hotel rooms or having sex in cars. The reason for this, a cynic might argue, is that these men are cheating on their wives and girlfriends.
