How is an industry not voluntary? I am not trying to be sarcastic; I am trying to understand where your argument is coming from. Regarding mass ED - here are two studies/articles on that:

Another item, how is a wage financial coercion? That doesn't make any sense. Stealing from someone if they don't do something is financial coercion; wages are monies paid for a service.

Also, porn induced sexual exploration is not strictly a male phenomena (see links below). Sexual tastes vary over time. That people expect or prefer certain acts now does not make them bad. What existing previously sexually is not somehow authentic (e.g., pederasty in Ancient Greece).

I think my biggest disagreement with you is not about whether it is good or bad (that is a totally subjective preference - some people will be supportive of porn, others will find it repugnant. Where I disagree is that it is largely coercive. It isn't. Some people make choices they later regret; that, however, does not make it definitively coercive. Some people are coerced into porn, but some people are also coerced into making clothes; that doesn't making clothing a coercive instrument.
