Well, my friend lives in the north, away from all of the hullabaloo. I told him if I didn't get into a program I was very excited about, I would come to the Canaries and be his love slave... Well, I didn't get into the program... LOL. He did tell me his apt ios not near the Gran Canaria "action" area... but the beach dunes were always popular if I got bored.
I've heard what you mention about Tenerife... many gay men live there, but it's more of a relaxed place for living.
I actually went on a spiritual retreat in La Graciosa a couple years back. The guy who put it together is a Cuban American, named Arnie, whose ancestors are from the Canaries. He keeps an apartment in Tenerife and told me a little bit about it.
