Using this data, Moors says she has found that people engaging in poly relationships are lower on anxious attachment and avoidant attachment compared to others.

However, she points out that this is a correlational finding. It could be the case that only secure, non-anxious, non-avoidant people are attracted to this lifestyle. What the psychological profiles of CNM people might suggest is that they have emotional needs that cannot be satisfied by one person.

But poly people have high highs and low lows. They might be people who need both things simultaneously and it is hard to experience those things with only one partner. A primary partner who is nurturing is unlikely to also be exciting in an erotic way. That said, there is very little in the way of a profile that you can build about CNM people, according to Moors. She says that there is no correlation between age, income, location, education, race, ethnicity, religion or political affiliation and CNM in her research.

People who identify as lesbian, gay or bisexual are more likely to be CNM, but that is the only pattern. For something that seems to span all walks of life, there is still a relentless stigma associated with non-monogamous lifestyles. Moors gives the example of how normal it is to think of platonic or familial love as endless, yet for some reason we consider romantic love finite.

How many best mates do you have? That would be a ridiculous thing to say. We ask a lot from our partners. We expect them to be our life coach, best friend, confidant. Perhaps we would be better off by spreading our needs between more than one person. Join one million Future fans by liking us on Facebook , or follow us on Twitter or Instagram.

The benefits of having many lovers. Share using Email. By William Park. We often see a relationship as an exclusive understanding between two people.

But this norm is increasingly coming under scrutiny as people find other ways to redefine romantic love. Having a threesome is the most popular sexual fantasy, by some margin. You might also like: What is the future of sex? Why we need to be more emotional The surprising benefits of being blinded by love At what point monogamy began to occur in humans is up for debate.

The idea of a partner being distracted by another can induce panic in the most stalwart and confident. But insisting upon a fairly unreasonable standard lifelong exclusivity or else!

This is not to say that you or your partner will ultimately connect intimately with another person in any way despite adopting a new viewpoint about exclusivity. It is wise to negotiate some guidelines with your partner — about who or what type of person might be invited to look in on that sphere, for a moment or longer, and what might be acceptable ways to connect with another person e.

If you also discuss how best to talk about it, this approach can go far in keeping your relationship truthful, transparent and trusting — making the need for a dealbreaker that much less relevant altogether.

Note: Please also check out our companion article, Top 10 Reasons for Being -- and Staying -- Non-Monogamous , in which we state: "Both monogamy and non-monogamy have their pros and cons; in both posts, we've tried to focus on the pros. Neither is an attempt at telling you how to be, but rather an encouragement of who you are and how you choose to be.

Sex can improve with time. Monogamy isn't just about marrying off before everything starts to sag. Age can also mean that you get to know your body better, you become more comfortable in your own skin, you leave youthful insecurities behind, and your partner learns your body so well they could navigate you blindfolded.

Given enough time, you and your partner can discover untold routes to your happy place. Why would you want to keep starting from scratch and having to break out the instruction manual all over again?

Cuddling comes naturally. There's no awkward pre-sleep shuffle as you try to find the best spooning position that will be comfortable all night. After years together, your bodies just naturally fall into place around each other. Peace of mind about STDs. Assuming both of you are true to your vows of sexual fidelity, then you don't have to worry about contracting any or any more sexually transmitted infections.
