In 1977, Ahnold conducted an interview with Oui Magazine, a now-defunct Playboy rag. Some pretty eyebrow-raising stuff can be found therein. While much of it is fueled by bravado, it's still not what I personally want to see in a guy who could very likely be the governor of my state for the next four years.
For example:
"Bodybuilders party a lot, and once, in Gold's--the gym in Venice, California, where all the top guys train--there was a black girl who came out naked. Everybody jumped on her and took her upstairs, where we all got together." Asked by Manso if he was talking about a "gang bang," Schwarzenegger answered, "Yes, but not everybody, just the guys who can fuck in front of other guys. Not everybody can do that. Some think that they don't have a big-enough cock, so they can't get a hard-on. Having chicks around is the kind of thing that breaks up the intense training. It gives you relief, and then afterward you go back to the serious stuff."
