Online-dating behemoth OkCupid is adding a feature tailor-made for polyamorous people. The new setting, which became available for some beta users in December, allows users who are listed as “seeing someone,” “married,” or “in an open relationship” on the platform to link their profiles and search for other people to join their relationship. It will be rolled out to all users on Friday.

The move comes in response to a rapid uptick in the number of OkCupid users interested in non-monogamous relationships. According to the company’s data, 24 percent of its users are “seriously interested” in group sex. Forty-two percent would consider dating someone already involved in an open or polyamorous relationship. Both numbers represent increases of 8 percentage points from five years ago. The number of people who say they are solely committed to monogamy, meanwhile, has fallen to a minority of all users, 44 percent, down from 56 percent in 2010.

“It seems that now people are more open to polyamory as a concept,” said Jimena Almendares, OkCupid’s chief product officer.
