Since every individual carries out any job to earn money, he practices prostitution to all intents and purposes. Selling your sex organ is no different than selling any other part of your body, like your voice, brain, muscles, and more, just to get money.
Not all work is paid!
But no, not all paid work is prostitution. Only when something personal is used for commercial ends does it become even figurative prostitution.
And literal prostitution is even narrower, narrow enough that it doesn’t include all sex work. That’s right, not even all sex work is prostitution.
