In rush so apols for rambling but
I just don't think it's possible to separate the watching bit from the knowing-what's-going-on-in-the-porn-industry bit.
You would have to be from Mars - or not care at all - not to have come across the idea that some women are being physically forced or forced in ways that go beyond being 'troubled'- for example by need to repay drug debts to pimp, off-camera emotional abuse, general sense of being in way out of your depth in organized crime. The pimp=the dealer= the photographer etc
And once you've absorbed that concept, it's also impossible not to realise that of course these girls don't have 'abused' written in marker pen on their bodies as a handy way of differentiating who is, and who isn't.
Which means that you know you don't know which model has been abused. If you continue to wank over them, it means - fundamentally - that you acknowledge you don't care which is abused, and which not.
I would suggest that this is, for many - and without even being aware of it - a subtext to the process of arousal, but I know many won't agree.
Sophable - I just can't agree with you. In comparison to the extent to which the porn industry is changing in the opposite direction, ie towards in increasingly brutally-expressed misgogyny, the impact of 'feminist porn' is utterly minimal.
And in any case, it's typical of the the principle of licensed dissent, in which a power structure allows the contained expression of opposition in order to prevent the overthrow of the whole system.
