Many of us might call having a long-term relationship with more than one person cheating. But for those who are polyamorous and proud, monogamy is so last century. The 11th annual Poly Pride Weekend celebrates these open-minded lovers with several events throughout the weekend. On Saturday from noon to 6, comedian Kelli Dunham hosts the free kick-off rally at the Great Hill in Central Park (enter at Central Park West and 106th Street), where you can hear about the latest research, law, press, and art devoted to the polyamorous movement. Later, dance the night away at the Infinity Party at the Ritz. Then snuggle up with strangers today at the Super Massive Cuddle Party at 1 p.m. at the LGBT Center.

Sat., Oct. 8, noon; Sun., Oct. 9, 1 p.m., 2011
