Sex is a big part of most romances, whether a marriage or a more experimental union. A recent survey of Europeans shows that people in the most sexually liberated partnerships aren’t having the best time. Monogamous couples reported that they were the most sexually satisfied of all the groups in a large, representative survey conducted in March 2017.
Among the 1,885 people who said they were in monogamous relationships, 82% reported that they were broadly satisfied with their sex life. That compared to 80% of people in a marriage, civil union or other legal partnership, while 71% of people in open or polyamorous relationships said they were fulfilled.
