"People in Hollywood don't have that much sex, or at least I don't"

In this quote, Rosario Dawson is most likely referring to the typical stereotype that individuals in Hollywood engage in excessive amounts of sexual activity. She is mentioning that this stereotype is not true, a minimum of not for her personally. By saying "or at least I do not," she is indicating that she can not speak for others in Hollywood, however from her own experience, she does not engage in as much sexual activity as the stereotype recommends. This quote could also be interpreted as Dawson challenging the idea that individuals in Hollywood are promiscuous, and asserting that she does not conform to this stereotype.
