There are four major types of prostitutes; streetwalkers, child prostitutes, house prostitutes, and call girls.  It is important to remember that, in most of America, prostitution is criminalized.  Like many criminals, prostitutes are often opportunists and, therefore, not locked into one particular form. Prostitution is often associated and includes other types of deviance such as drug use.  As you read through the types of prostitutes, keep in mind the fluidity of prostitution as a criminal activity, which may enable a prostitute to move through the different categories as well as into other crimes.
