If you're a couple in Maryland who has talked about inviting a third person into your relationship, you already know that finding the right person can be more complicated than it sounds.
You may be looking for someone comfortable dating a couple, who understands open relationships, or who simply wants to explore a three-way connection without unnecessary drama. At the same time, if you're a single person interested in couples dating, you probably want to know what the couple expects before you get involved.
That is where unicorn dating comes into the picture.
A unicorn is generally a single person who is interested in connecting with an established couple. Some people use the term for a casual three-way experience, while others are interested in an ongoing relationship or something that develops naturally between all three people. There isn't one correct version of unicorn dating. The important part is that everyone involved understands what they want.
Why Maryland Can Be a Good Place to Explore Unicorn Dating
Maryland has more than 6.26 million residents, according to the U.S. Census Bureau's July 2025 population estimate. The state's 2024 American Community Survey also counted about 2.40 million households, including approximately 155,700 cohabiting-couple households.
Those numbers don't tell us how many Maryland residents are interested in threesomes or non-monogamous relationships. There isn't a reliable government survey that measures that. What they do show is that Maryland has a large and varied population with many different household and relationship arrangements.
There is also an active ethical non-monogamy community around Baltimore and the wider Maryland–D.C.–Virginia area. For example, Baltimore-area organizers host gatherings for people interested in polyamory, open relationships, relationship anarchy, and other forms of consensual non-monogamy.
For someone interested in dating a unicorn in Maryland, or for a unicorn interested in meeting a couple, that kind of community can make it easier to find people who are already familiar with non-traditional relationships.
But meeting someone is only the beginning.
What Couples Should Consider Before Dating a Unicorn
The biggest mistake is approaching a unicorn as if they're simply filling an empty position in an existing relationship.
A third person has their own preferences, expectations, boundaries, and feelings. If you're a couple, talk privately first about what you both want. Are you interested in something casual? Would you consider seeing the same person regularly? Are emotional connections welcome? What happens if one partner develops stronger feelings?
You don't need to have every answer before meeting someone. But you should be able to have an honest conversation about the important ones.
It also helps to give the single person room to communicate directly with both partners. A healthy three-person connection shouldn't feel like one person is being interviewed by a couple.
What Unicorns Should Look For
Dating a couple can be exciting, but it should work for you, too.
Before agreeing to meet, ask questions. Find out whether both partners are genuinely interested, what they're hoping to explore, and how they normally handle boundaries and communication.
Pay attention to whether you feel heard. If everything seems to revolve around what the couple wants and there is little interest in your expectations, that's useful information.
There is no need to rush into meeting someone simply because the chemistry looks good online. A few honest conversations can tell you a lot.
How 3Somer Helps Couples and Singles Connect
We created 3Somer for people who don't necessarily fit the traditional one-to-one dating model.
Couples can present themselves as a couple and explain what kind of connection they're open to. Singles can create their own profiles and connect with couples who are interested in meeting someone like them. The app also provides search and matching tools designed around alternative dating, rather than expecting everyone to squeeze a three-person dynamic into a conventional dating profile.
That makes a difference when you're trying to find a unicorn in Maryland. Instead of matching first and explaining your relationship structure later, you can start with a clearer understanding of why you're both on the platform.
You can explore people locally, including around Baltimore, Annapolis, Silver Spring, Columbia, Rockville, and other Maryland communities, while also keeping your options open if you're comfortable meeting someone farther away.
For singles, 3Somer offers the same advantage from the other side. You don't have to wonder whether a couple is actually open to meeting a third. Their presence on a dedicated threesome dating app already provides useful context.
A Three-Way Connection Should Work for Three People
There is no formula for a successful threesome or unicorn relationship.
Some connections remain casual. Some become recurring relationships. Others develop into something much more emotionally involved. And sometimes three people meet and simply realize they aren't a good match.
That's normal.
What matters is that nobody is pressured into a role they didn't agree to, and everyone has the freedom to say yes, no, or not yet.
3Somer has been part of the threesome dating space since 2016 and has been featured or covered by publications including Men's Health, YourTango, The Irish Sun, Inverse, Refinery29, The Mirror, Cosmopolitan, and Bustle, among others.
Whether you're a Maryland couple ready to meet a unicorn or a single person curious about dating couples, 3Somer gives you a dedicated place to start.
Create your profile, be upfront about what you want, and see who you meet in Maryland.
