I think pornography is the worst kind of prostitution, because if you buy it, most of the money will not get to the ones that excite you, but to rich capitalists. At the exception of Fuck the Forest.
So, download it but not buy it.
About prostitution, it can be a fast way for a smart and beautiful woman to become rich very fast. I meet some, but they are the exceptions in Western countries. In some other countries, peoples have a much more open and natural feeling with sexuality than in the West, and not only they don't feel guilty, but they see that as a good way to make money if other peoples, in most cases rich foreigners, are willing to pay for a so natural thing.
Last but not least, historically prostitution did appear in the Ancient time, and at the same time than what we call civilization. Before that, both the polygamy and the polyandry was normal, and when our "modern" religions did appear with their cohort of war, warriors, merchants and slaves. Patriarchy replaced both matriarchy and group marriage. In consequence, the women status went down to something between the pig and the slave. Polyandry was oppressed, nut not polygamy. At best a woman could succeed as a sacred prostitute.
What is very funny is that women did not wait to take their revenge. A new avatar did appear in history at the same time: the cuckold. The cuckold is the corollary of the warrior, and the prostitution is one of the corollary of the lost of the feminine social status and of a society based on the exploitation of nature and of other human beings.
All that imply it is a waste of time to fight against prostitution. To end prostitution, we must end what we call civilization and build a whole new society based on respect of nature and of respect of each others.
