Going off what Christy said, it SURE sounded like they enjoyed each other during their fling.
Shame they never had sex IN FRONTda0 of the cameras. But I guess it doesn't matter to them. Just as long as they were able to climb in the sack with one another. In front of the cameras or not.

Did they like each other? Was it a test drive?

Christy has revealed on Playboy radio that she and Rocco did get together offscreen, but never infront of the cameras. She said it was a few months following their first photoshoot, which according to her autobiography, was the the day following her shooting "Hot in the City" for Canyon Video.
So yeah, they did it. Just not for the cameras.
Which is unfortunate for us.

Christy Canyon performed two separate photo shoots with Rocco. The first photo shoot involved a menage-a-trois M-M-F situation with simulated, soft-sex scenes. The other photo shoot involved her and Rocco alone with very graphic, insertion everywhere scenes. And yes, the photos are on the internet and not lost in time. They never performed a live taped scene together, but we'll most likely never know if they got together in real life. Christy is on record as having slept with a lot of her co-stars in real life. This is way too much information to know about one person you don't know in life.

They never appeared in a movie together (unfortunately). Christy finally retired shortly before she was due to make a film with him.
