Why couples and singles choose 3Threesomes
Every part of the platform is built around one kind of connection instead of trying to bolt it onto a mainstream dating app.
No explaining yourself
Every profile here already understands non-monogamy, so the conversation starts where mainstream apps leave off.
Couples and singles, both first-class
Search and messaging are built for pairs looking for a third and for singles looking to join one, not retrofitted from a one-on-one app.
Privacy at your pace
Reveal photos and details gradually as a conversation develops. Discretion is the default, not a setting you have to dig for.
Consent, always
Clear communication and mutual respect are the baseline for every connection made here, not an afterthought.
New or experienced, welcome either way
Whether this is your first time exploring non-monogamy or you have years of experience, the community holds space for both.
A community, not just a swipe deck
Members here are working toward the same kind of connection, which makes for fewer mismatched intentions and better conversations.
How it works
1. Create your profile
Set up a profile as a couple or a single, and say clearly what kind of connection you're looking for.
2. Browse and connect
Search by location and intent, and start conversations with couples and singles who want the same thing you do.
3. Meet on your terms
Take things at your own pace, reveal what you're comfortable with, and meet when it feels right for everyone involved.
Built for a kind of dating mainstream apps weren't
Most dating apps are built around one person meeting one other person. That works fine until you're a couple looking for a third, or a single who wants to date a couple, at which point the whole format starts working against you instead of for you.
3Threesomes exists because that gap is real. Couples can build a shared profile and search together. Singles can find couples who are actually looking, instead of guessing from context clues on a mismatched app. And because everyone on the platform already understands non-monogamy, conversations start from a place of shared intent rather than explanation.
The result is a smaller, more intentional community across the US, UK, Canada, and Australia, where the people you meet already want the same kind of connection you do.
Frequently asked questions
What is a threesome dating site?
A threesome dating site is a platform built specifically for people open to three-person relationships and non-monogamy, including couples looking for a third partner and singles interested in joining a couple or forming a triad. Unlike mainstream dating apps, everyone on the platform already understands and accepts this kind of connection.
Is 3Threesomes only for couples?
No. 3Threesomes is built for couples looking for a third partner and for singles who want to meet couples or form a triad. Profiles reflect whichever situation applies.
How is this different from a regular dating app?
Mainstream dating apps are built around one-on-one matching and rarely account for existing couples or non-monogamous intent. 3Threesomes is designed around that reality from the start.

No. The community includes people who are new to non-monogamy and exploring it for the first time, alongside members with years of experience.
