Open Relationships Are Less Sexually Satisfying Than Monogamy, Study Finds

Around 82 percent of people in monogamous relationships said they were satisfied with their sex lives, while only 71 percent of polyamorous people said the same.

Stepping into an open relationship can often times help people survive long-distance relationships or work through jealous feelings, but according to a new study, it doesn't always lead to a satisfying sex life.

According to Quartz, a Berlin research group surveyed roughly 11,000 people from all over the European Union and found that monogamous and married couples are significantly happier with their sex lives than those in open or polyamorous relationships.


The findings, which were released in May, found that 82 percent of those in monogamous relationships were satisfied with their sex lives, beating out all other romantic setups. About 80 percent of married folks reported being sexually satisfied, while only 71 percent of those in open or polyamorous relationships felt the same way.

Those numbers, unsurprisingly, take a sharp, sad nosedive when you look at single people. Just 48 percent of people who weren't in a relationship (but weren't looking for one) reported being happy with their sex lives, while only 40 percent of singles who were looking for love were sexually satisfied.

But when it comes to having a happy and fulfilling relationship, sex isn't always everything. According to a study published last month in Perspectives on Psychological Science, researchers from the University of Michigan found that people in open or poly relationships were generally much less jealous—and significantly more trusting—than their monogamous counterparts.

Dalia's survey also found that regardless of what kind of romantic arrangement they're into, people are having the best sex of their lives between the ages of 25 and 30—and that's both men and women. On top of that, Spaniards are having the most satisfying sex, while only 23 percent of people in Poland said they were "very satisfied" with their sex lives.

While the survey says a lot about sex in the EU, it didn't look into any monogamous, married, or polyamorous relationships in the US, probably because most American millennials don't really seem that interested in fucking anymore.
