Sex party!!

This isn't exactly hobby related, but I wasn't sure it fit the sandbox.
So.. Here goes..
I recently snagged an invite to an anything goes sex party while traveling South.
It was one where everyone's face was masked and going in I had no idea what to expect. So, being an adventurous guy I went with it.
There were all types of women there. All shapes and sizes and all horny and as advertised. Anything went.
It was something out of a 70's orgy scene in porn.
It was hot to watch, but I only partially participated. It was kind of overwhelming and a bit intimidating. I have access to another and next time I won't be shy.
I was curious how many of you guys and girls have been involved in such a thing.
Do they happen locally? Thoughts? Comments?

There was a girl who advertised such parties here at one time, think she is off writing a book or dancing now though...
Not sure if it is the same kind of thing but in a previous life I found my self in a small apartment overfilled with swingers of all ages and shapes, the initial "adventures ahhh" feeling faded fast as the smell became more...."robust". Have not had any desire to try again but the initial idea sounds cool in abstract.

Would be fun

It would be too easy to pick me out of the crowd with my 1.3" f dangling death.

I've done the apartment thing with mattresses on the floor and bodies scrunched together and the smell of sex in the air. Back in my wilder days I attended those types of parties twice a month.
This was in ajoined room loft apartment. It was a large venue and set up
similiar to the movie "Eyes wide shut". That is what it reminded me of anyway.
It was in Austin which like a hotbed of swingers and sexual people anyway.

Swingers so this kind of stuff from time to time.
