I will be in Crete from beginning till mid of September as I come from there. The place does not advertise it officially about sex clubs etc but there are some known hotels that offer swinger packages for vacations (though I am not aware of their names) mostly located near the super touristic sites in Heraklion Rethymno and Chania. The place is great for vacations especially the south side of the island where there are also many nudist beaches!
Feel free to contact me for travel suggestions or if you would be up for some fun day trips!
