There are no swingers clubs or nudist beaches in Thailand. They are against the law, and the law is enforced.
I have written a guide for newbie Bangkok sex tourists. Let me know if you would like a copy. It will help you to hit the ground running.
Thank you for your reply! I have been to Thailand four times now so this will be my fifth. I prefer having good times / socials with couples with the swinging ethos than the norm of bar girls.
As Stride said , it's against the law and if caught you will be deported etc.
Of course there are swingers in Thailand but you'll need to use other websites / contact points etc.
A visit to the camel toe in pattaya might assist you too .
