mike big....
You are in LA....there are LOTS of places to choose from for a swingers party.
A full on GB party happens once a month at ClubTaboo (See Club Listings here). Go to watch and keep your clothes on if you like. We have just watched and it was a blast. Fucking and sucking ruled the night with lines waiting to get to different women.
Totally different than regular parties.
Go as slow as you need to. Let the slowest person set the pace you two move at. Have fun and be safe.
