It is so easy to think we can detach ourselves from our actions; with reference to that video of the male porn star you posted, Matt. However, we are not capable of doing that. That is also why more US soldiers committed suicide, after coming home, than the number of soldiers who died in Vietnam. We, as humans, can get trauma and PTSD from bad experiences, and I also read that many former porn stars committed suicide.
I do not believe porn should be banned, but it should not be abused like alcohol should not be abused. Individuals should regulate such usage of substances, and not the state.
