I can't write the whole essay for you, but I can at least point you to the right direction.
Prostitution are the acts of sexuality for both man and woman who are willing to have sex with customers willing to pay them. This could also relate to people wearing revealing and scandalous outfits to show off more skin and censored features.
I suppose you can list some real-life events based around prostitution.
For your closing sentence, add reasoning to why prostitution should be banned from society, and clubs or secret ''underground'' organizations are prohibited from doing these tasks.
