But that's very different from a JO group. Two different things.
So if you want you can start a thread called "Starting a weekly orgy group in NYC/Brooklyn" and watch it go nowhere just like this one.
If OP (or whoever can host) really wants it done they'd set a date for a week or two or three from now, and get people to commit to show up at that time. Simple as that.
I can't host and I'm a first timer, so my commitment level is somewhere around "show up, look around while trying not to feel awkward, and maybe whip it out if I feel comfortable enough, or leave after 5-10 minutes of awkward walking around."
So you'd probably want a more seasoned veteran putting things together. I'm testing the waters.
So, is someone gonna do it??
