:I understand it requires existence (as you noticed I had a technical complication with the categories) There are more articles that would fall under 'sex-economy', such as Neo-Reichian massage and some more that I will create in the future. The problem with 'sex economy' is that it is too easily confused with the completely different Sexual economy. Do you think that is enough reason to justify including the hyphen (apart from that that is the way it is defined and used in the literature). And any comments on the health categories?
