I went to Costa Rica with some of my close swinger friends and we found a boat charter that said they were cool with driving us around naked and having sex on their boat. It ended up turning into us girls sucking everyone husband's and boyfriends cocks. But then everything went south, because someone called the cops on us and the sent the Costa Rican Coast guard out to our boat to let us know we can't have public sex on it lol. It was worth a shot! At least you can't say we didn't try hard
