If you mean consenting adults looking for group-sex/ENM connections, my top pick is Feeld. It specifically supports couples, linked profiles, desire/interest filters, and group chats of up to 25 people.
FetLife — better for kink communities, local groups, and events than straightforward matching.
SwingLifestyle (SLS) — more specifically oriented toward the swinger/lifestyle scene.
Meetup — useful for finding local ENM/poly social groups and events, rather than directly arranging hookups.
For NYC specifically, Feeld is probably the easiest starting point; has also hosted NYC community socials, although those events aren't necessarily sex parties.
