I don't think this has ever been done before but I think it would be a good idea to try. One big reason would be that it would be more comfortable to the men on the set , I would think. I've heard in the past that some people complain about the lack of alot of male talent in the porn industry. That they see the same guys over and over again, sometimes for more than 20 years in the industry. Well imagine if a new guy trying out for porn was on the set and had all the hot lights and crew around him, and he was trying to be sexually excited in front of his female co-star. It would be uncomfortable with alot of male stage hands and cameramen a foot away from your ass. Now if it was an all female crew behind the camera, and a female diector, and female lighting etc. , it might enable alot of new male talent to perform well under these conditions. It probarbly isn't a possibility, but I would like to see how this would turn out.
I have heard of female directors of porn before, but what I am getting at is an all female presence behind the scenes of the film. Just my thoughts.
