Experts believe that men visit prostitutes for numerous reasons. Firstly, it's never been easier to find and contact sex workers due to the internet and legal brothels opening up every year. Secondly, a growing number of men are often in a stable relationship, but will still visit prostitutes to perhaps play out fantasies or domination that they can't get at home.

Single men may visit prostitutes because they may see it easier than playing the dating game. Men can pay for sex in a straight forward transaction, and they get what they want. There are also no emotional strings attached.

Having sex with prostitutes can be a thrilling and illicit experience for a man, which gives them a sense of power and control. Some experts argue that for certain men, the act of visiting a prostitute has become an extension of the high-adrenaline lifestyle commonplace today. For other men, the "cheapness" of the whole act is a turn-on for them.

If a man is in a relationship with someone and visits prostitutes, is it seen as cheating? Can a man declare that he didn't cheat because he has no emotional connection to the girl? Or is having sex with another person at any time cheating, whether there is an emotion connection or not?

Currently, Sex Addiction isn't recognised by any official diagnosis in the American Psychiatric Association's 'Diagnostic and Statistical Manual of Mental disorders (DSM). But since Tiger Woods was publicly shamed by his self admitted 'Sex Addiction', this new disorder has been headlines around the world. Typically, sexual addiction refers to an individual who is unable to manage their sexual behaviour. Skeptics believe that it is a myth that the phenomenon actually exists, but is simply an repetitive action carried out due to cultural and other influences.

Could Sex Addiction be the new "excuse" for having an affair behind your partner's back after they are caught out? Does this new term give cheating partners an opportunity to justify their behaviour because it's "not their fault"? A chronic adulterer who gets caught might hide behind the term.

Anything to do with sex is controversial. Everyone has an opinion of where the boundaries lie between what is normal and what isn't. With the increase in sexual provocation within our society, it has spawned an increase in individuals engaging in unusual or illicit sexual practices such as using phone sex services, prostitutes and internet pornography.

Either way, if a partner has what they term a 'Sexual Addiction', their obsession with meeting their sexual needs is extremely damaging to their partnership when it is searched for outside of their relationship.
