Gender difference is also another reason that may cause men to use prostitution services. It is said that males and females differ biologically. Men have more sexual drive than women do. This dissimilarity drives men to engage in prostitution. Moreover, the idea of having a wife and at the same time managing to have sexual intercourses with several women shows the “manliness” and illustrates that they are “real men”. This concept is well acknowledged among prostitution users (Re, 2002).
