No, a man using a woman for sex when she can not give consent is already called "rape" and is illegal, because we as a civilization understand that this causes significant trauma for individuals -- that is, it's categorized as "violence".
Buying services and goods, on the other hand, is not violent, like rape is, although we could see the fact of poor people (or all people, really) having to sell portions of their lives to strangers to survive as unfortunate and alienating. This is, I think, where Marxism comes from.
I think you misunderstood, because you missed the sarcastic tone that I perceived in the previous parent comment.
I agree with what you wrote, of course. I may not like the existence of prostitution, but in order to have others respect my strange preferences, I'll have to respect the strange preferences of others, as long as it's consenting adults doing things.
I think a large swath of the working population would disagree. Give up a 30% of my life to do something I would rather not do so that I don't starve? I guess I'll take that deal.
