#6 – 51% are ready to date someone that’s married

#7 – 1% of people +50 years old have been in an open relationship

This is a big indicator that even though open relationships have been around for more than 60 years it’s still the young people that practice it the most.

#8 – 90% say they are more happy after engaging in an open relationship

Which of course is super news. This means that 9 out of 10 who decide to try this are happy with the decision. So in other words, if you think about starting on something like this, it seems like a good idea.

#9 – 1 out of 5 are dating more than one person at a time

This belongs to the grey zone of what we characterize as open relationships. Still a bit fun to know that you probably have to be very explicit about whether you’re dating seriously or not. And the meaning of this. This is important for the ones who expect that “serious” dating means that you’re only together with one at that time.

The sexual desire together with a feeling of not being heard is what lets people start in open marriages.

#12 – Men are more interested in an open relationship (32%) than women (19%)

It’s typically men who have the biggest sex drive. This is also seen in open marriages. Also, men are more willing to try new things. The combination of this leads to the fact that men are almost 2x times more interested in open relationships than women.

#13 – If you’re in an open relationship you tend to have more sexual partners (avg. 7 partners) compared to the normal (avg. 4 partners)

Which of course makes sense since you’re more sexually active, and also seeking it more.

#14 – 16 states in the USA have made it illegal to have open marriages

This is also valid in other countries. In some of them, you can get the death penalty. So please be aware of the laws in the country you’re living in. It is important to say that most of the 16 states in the USA do not enforce these laws.

#15 – Millenials are most interested in open relationships (41%) compared to Generation Z (29%), Generation X (23%), and boomers (12%)

Millennials also called Generation Y were born between 1985 and 1996 and are the generation that are most into open relationships. Compared to Generation Z which is from 1997 to 2012 and Generation X from 1965 – 1980 and Boomers which is even earlier from 1946 to 1964.

So again an indicator that tells the story that open marriages and open relationships are for the young generation, right now.

• Using escort without the other partner knowing it
• Going to swinger clubs or finding other couples that are ready for swinging (partner swaps)
• Emotional affair, where you bond with another person, but without having sex (physical activities)

Conclusion

To summarize we do think that open marriages work. It just depends on the couples practicing it.

From our perspective and the data from the report, it shows that it’s important to communicate to ensure that both of you agree about what happens.

Remember that you love each other, and you started this together as a fun gimmick you could have together, just the two of you.
