Sex crimes are related to human instincts. As biological creatures, human begins have sexual drives and sexual urges. When these urges become uncontrollable, individual people are sometimes driven to acts that society does not approve of. These acts may not be criminal. But when the acts are criminal, the punishments are often very severe.
One of the most striking forms of sex crimes is prostitution. A centuries-old practice, prostitution is the selling of one's sex. Many cities have so-called "Red Light Districts" where prostitutes offer their services. When prostitutes are caught be police, they often do not face much jail time because they are seen as victims. But when clients of prostitutes (who are usually men, because prostitutes are usually women) are caught they can face severe jail time.
