What is Prostitution?

Prostitution is the act of exchanging sexual pleasure for money. Isn’t all sex an exchange of sexual pleasure for something? In the most quintessential terms, sex is a barter of pleasure for pleasure. Should sex without the intent of procreation be illegal? Is the “social ill” of prostitution unjustly illegal? What impact would legalizing prostitution have on the community and society?
I in one way say legalize it because you pay for it regardless. But at the same time there has got to be some restrictions. What? I don’t know. But I was just thinking the other day like Damn, if I could sell this shit……
