Quote: Having herpes wouldn't prevent them from working with other performers with herpes...just the ones who don't have herpes.
Problem with this is that the number of performers with Herpes are far more than those without. If that is the case, the new girls that come into the business without herpes are left with a small talent pool of male performers without Herpes.
Having said that, it would be as boring as seeing these new girls working with their boyfriends scene after scene because you would only see them with several male performers over and over.
