Prostitution is different from adultery:

Lack of sex-education, economic under-development, sexual molestation and rape are the reasons elaborating the premier reasons for this lewd occupation. Many pitiful women emerge into cities in search of a respectable job, but many of them are denied so, forced to become call girls, bar dancers or escorts, to live a life of slavery and torment. Although the human rights crisis of millions of sex-workers is a major issue worldwide, India continues to be a failure judicially and legislatively.
