I rent vacation properties in Barcelona, among other things, and the guy who cleans the apartments brought over the recent cache of hidden porn from one of my pisos on C/Muntaner, near the gay disco La Metro. I bring this up first, because most of my renters are gay. And the majority of them are groups of young men (4 to 6) who stay in the city for at least 2 months, if not more. Another amusing fact is they all tend to be from the UK or Germany.
The Germans tend to go for gonzo porn and when they leave they hide it in places I suppose they think no one will ever find it. We find it. The Brits tend to go for bisexual porn and just leave in on the shelf next to the DVD/TV area.
Among our recent "gifts" is a DEVILSFILM.COM DVD featuring Ariana Jollee called 65 Guy Cream Pie. It's a no condom gang bang where she takes on one guy after another. Amusingly, the porn actress seems really into it, but the buff young men standing around trying to work up stiffies are less aroused. As for me, I found it hysterically funny. She continually has to corral the men up and tell them what to do, occasionally conferring with the cameramen if they're getting good shots.
One word: stamina.
