I will be in Lisbon and Oporto the second week of October. Is there any couple o woman to show me around? If speak some Spanish would appreciate but not a must.
Yeah. Usually in some swinger clubes they allow a certain number of men, but they have access to specific areas, not where the couples are. But you can invite one and take him to the other areas if you want.
There are many places and clubes where you can go, about swingers clubes I recommend you Training Pedralbes and Oops. About nudist beaches, around Barcelona there are a few, depends what you are looking for.
