pros·ti·tu·tion prästəˈt(y)o͞oSHən/ Noun The practice or occupation of engaging in sex with someone for payment. The corrupt use of one's talents for personal or financial gain. payment [ˈpeɪmənt] n 1. the act of paying 2. a sum of money paid 3. something given in return; punishment or reward. Thought examples. Exhibit A: Married couple, wife stays in a home that is provided by husband, purchases shoes and dresses from moneys given to her by husband. They are married, you say, so it is acceptable, "Legal prostitution". Very well. Exhibit B: UN-Married couple, girlfriend stays in a home that is provided by boyfriend, purchases shoes and dresses from moneys given to her by said boyfriend. One could say prostitution, even though it is not cash, it is "something". Exhibit C: The Married couple from A is now divorced, ex-wife stays in a home that is still provided by ex-husband, purchases shoes and dresses from moneys given to her by ex-husbands alimony payment. Sure, the sex part is likely gone, but one can argue it is "residual" from having the sex. On a different angle, Prostitution is regarded as "the worlds oldest profession" and has been seen in animals where the male gives objects, food mainly, for sex. So sex with payment seems to be incredibly prevalent and broad, how can prostitution be unique and by extension a crime? Discuss.
