Trich – The Trouble-Maker STI Your Play Network Shouldn’t Ignore

Trichomoniasis (Trich) in Swingers & ENM Communities: Symptoms, Testing & Prevention

If you hang out in the world of swinging, ethical non-monogamy, or play parties, you’ve probably heard us talking about M Gen lately. She’s sneaky, quiet, and kind of a diva.

Now it’s time to meet her purple, drama-loving cousin: Trich.

What Is Trich, Exactly?

Trichomoniasis (aka Trich) is a sexually transmitted infection caused by a tiny parasite called Trichomonas vaginalis. It’s not a virus or a bacteria – it’s a protozoan, and it’s very good at starting trouble in vaginas, vulvas, and urethras.

Global health organisations estimate that Trich is actually one of the most common curable STIs in the world, with tens of millions of new infections every year. In the U.S. general population, studies suggest around 3% of women and 0.5% of men may be infected at any given time.

That’s the general population. Now let’s zoom in on high-activity sexual networks like swingers and performers.

Real Numbers: What We Saw in October

Because we like real data (and not just vibes), we looked at recent testing numbers from two different groups:

• STD Hero – Swingers / non-monogamous community: In October, about 0.9% of the swingers tested had Trich
• Talent Testing – adult performers: In the same month, around 0.2% of performers tested positive

Same infection, different communities, different rates. What does that tell us?

• Trich is absolutely present in swinger and non-monogamous communities
• Communities that test often and consistently (like porn performers) seem to keep prevalence lower
• If your testing panel doesn’t include Trich, you may be blissfully unaware of what’s circulating in your play network

The Sneakiest Part: Most People Don’t Have Symptoms

Here’s the bit a lot of people don’t realise: around 70% of Trich infections are asymptomatic. That means most people who have Trich:

• Don’t feel sick
• Don’t see anything obviously “wrong”
• Keep playing as usual… and may keep spreading it through the network

When symptoms do show up, they can include:

• Itching or irritation of the vulva, vagina, penis, or groin
• Unusual discharge (sometimes frothy or with a stronger odour)
• Burning or discomfort when peeing
• Pain or discomfort during sex

But relying on symptoms alone is like relying on a “vibe check” for STIs, it feels reassuring, but it’s not actually data.

Why Trich Is a Big Deal for Non-Monogamous Folks

1. Trich Makes It Easier to Get Other STIs

Trich doesn’t just cause irritation for the sake of it. That inflammation and disruption to the genital tissues can actually make it easier for other infections to take hold. In other words:

Trich is a risk amplifier.

If Trich is quietly hanging around in your network, it can increase the risk of acquiring or transmitting other STIs, including some of the ones we’re much more scared of.

2. It Creates “Hidden” Risk your community

Because so many people have no symptoms, Trich can move through an open sexual community unnoticed. You might feel totally fine, get a negative standard panel (that doesn’t include Trich), and assume everything is clear.

But if your panel didn’t test for Trich or for other “emerging” or less commonly screened STIs like Mycoplasma genitalium (M Gen) then you don’t actually have the full picture.

3. The Good News: It’s Curable

Trich is annoying, but it’s not invincible. With the right antibiotics (usually metronidazole or tinidazole, prescribed by a doctor), it’s generally very treatable. The catch? You need:

• Accurate testing to pick it up in the first place
• All relevant partners to be treated
• To avoid sex until treatment is complete (and ideally, until you’ve re-tested if your provider recommends it)

Are You Actually Being Tested for Trich?

Here’s where a lot of people including very responsible, test-regularly swingers get tripped up. Most “standard” STI panels focus on:

• Chlamydia
• Gonorrhoea
• Syphilis
• HIV (sometimes Hep B/C)

All essential. But quite a few panels do not automatically include Trich. And they may not include M Gen, or oral and anal swabs either. If you’re only doing a basic genital urine or blood panel, you could be missing:

• Trichomoniasis (Trich)
• Mycoplasma genitalium (M Gen)
• Rectal/anal infections (many STi’s are site specific)

Why We Love Working With STD Hero

Full disclosure: we’re proudly partnered with STD Hero because they actually understand non-monogamous networks. They offer panels that include:

• Trich testing
• M Gen testing (for FREE in each STI panel)
• Oral and Anal Swabs

And the best part? They’ve recently rolled some of these “extra” tests like M Gen into their packages at no additional cost. If you use the code Libertine at checkout, you’ll also get 10% off your next test: www.stdhero.com

Safer-Sex Strategies for Swingers & ENM Communities (Trich Edition)

1️⃣ Make Trich Part of the Conversation
Ask, “When were you last tested and did your panel include Trich?” A “full panel” often misses it unless you request it.

2️⃣ Know Your Testing Cadence
Test every 3–6 months, or after new partner introductions or big events.
Include oral and anal swabs, and consider adding M Gen for a fuller picture.

3️⃣ Barriers Still Work (and Help More Than You Think)
Condoms, internal condoms, and toy covers can reduce Trich transmission, even when symptoms are absent.

4️⃣ Treat the Whole Network if Positive
Take the full course of treatment, notify partners, and avoid play until everyone has been treated. Reinfection is common if partners aren’t included.

5️⃣ Look Beyond Symptoms
Up to 70% of Trich infections are asymptomatic, so feeling “fine” doesn’t mean you’re all clear. Let testing, not symptoms guide your decisions.

Where Trich Fits In With M Gen and the Bigger Picture

We’ve talked before about M Gen (Mycoplasma genitalium) as an emerging STI to watch, especially because of antibiotic resistance issues. Trich sits in that same category of “less talked about but important” infections.

Neither Trich nor M Gen always show up on basic clinic panels. Both can be asymptomatic. Both can quietly travel through a play network. And both can be addressed effectively when caught early and treated properly. If you haven’t already, you can read our deep dive on mGen here
