Prostitution (by and for adults, not minors) should be legal, in keeping with the libertarian principle of freedom for consenting adults to do as they wish, even if it’s immoral according to my beliefs. It should be free trade without big government intervention. Imagine person A offering to do something for person B, and person B offering to give something to person A in return. This is a voluntary interaction and should be legal. Then, person C (government, or anyone) comes in and says “no” and forcibly stops the voluntary activity because they think that they are the boss of everyone else. That’s how the prohibition of prostitution works, and in this case the something traded is sex and money. To forcefully violate the freedom of the traders is immoral. Besides that moral argument of freedom, outlawing prostitution has terrible effects on women because it forces that market underground where it becomes more dangerous and women are controlled by violent pimps and sometimes forced into sex slavery. And, legalizing it usually takes the STDs and drugs out of it. You may have good intentions by wanting to outlaw prostitution, but your intentions are worthless compared to real effects. Here is a good video by ReasonTV describing the benefits of legalizing prostitution.
