Walter asks: "My wife and I are wondering if you can suggest any dating sites for polyamorous couples, as she and I are looking for a woman to have a monogamous triad with.
I have looked and looked and have basically run my head into a brick wall with this. You've got a lot of company in your search for a single gal to join you and your wife for a long-term, monogamous partnership Walter, so while I'll share the websites that I know of to suit your needs, there are few guarantees you'll actually find what you're after. In many polyamorous communities, single women wanting to join a couple for an exclusive triad are often called "Unicorns", as they're both rare and beautiful to behold.
Having said that, I know of a significant number of partnerships with this kind of dynamic, so it's more than just a fantasy you're chasing.
Ok Cupid offers a curious and fun mix of singles looking for all sorts of partnerships, and for whatever reason, it has attracted a significant number of polyamorous singles and couples, looking for other folks to share their love with.
Perhaps it's the flexibility in their gender and relationship statuses - for instance, you can list yourself as 'attached' as well as 'looking' at the same time - or maybe it's the open feel of the site that welcomes folks of all loving beliefs to its folds.
Of the poly singles, couples and groups that I know of, Ok Cupid is mentioned only second to Fet Life as their dating site of choice, and likely because it's one of the few free dating sites around that cater to this niche.
More » The folks who run Fet Life, as well as many of its members, may cringe at joining the ranks of the dating sites listed here, as the alternative lifestyle social networking site makes a point of staying away from typical 'dating' searches and features found easily at all of the other websites on this list.
Still, I've found a significantly higher-than-average number of poly folk on Fet Life, with a staggering number of local groups catering to those seeking multi-partnered relationships.
Also free, it does require everyone joining over the age of majority in their area, if only because of the obviously adult nature of the site (many would consider Fet Life pornographic in nature).
More » Okay, so I've deviated a bit here, offering up local resources instead of a specific dating site, per say.
The thing is, networking is key in this kind of search, and oftentimes you'll find meeting folks at real-world events the best way to communicate and connect with like-minded individuals.
With that in mind, try searching Meetup.com, Fet Life (see above), Facebook, and Loving More for resource, groups and connections.
