For a long time prostitution has been illegal and looked down upon but the simple fact of the matter is that legalization of this as a profession would not only ensure better safety of those who end up doing it anyways but would also create viable jobs and thus become taxable.
Only we own our bodies, and we should be allowed to sell them if we should chose to do so without fear of legal action and if prostitution were legalized we would also be able to sell our bodies with less fear of abuse and knowledge that we would have protection against those who would abuse us anyways.
