One in four people in debt in the UK blame their financial woes on spending money on sex.
The finding is based on data from The UK Insolvency Helpline that stated that spending money on sex was the third most common reasons for people to go bankrupt.
The leading causes were alcohol, drugs, and a shopping addiction.
According to the helpline, out of all its clients, 10,251 - the equivalent of one in four people - who called in between January and September 2007, admitted they had paid through their pockets to watch porn, visit a lap dancing club or a brothel.
The clients were aged between 25 and 49, with the average age being 42.
UK Insolvency Helpline said that sex addiction can take a toll on their professional lives, with people losing their jobs or getting into debt as a result of having to pay legal bills relating to sexual harassment.
The problems can also lead to divorce or separation and their associated financial probles.
"We feel that as computer, satellite porn and prostitution becomes more widespread it will give more men unrealistic expectations of their love lives and threaten couples' relationships," the Sun quoted Richard Sorsky, social policy co-ordinator at The UK Insolvency Helpline, as saying.
"This has become apparent due to the number of men admitting to using prostitutes and our referrals to divorce or marriage counselling organisations."
According to the helpline, three-quarters of the people who called in were single men, with the rest either married men or women or single or separated women.
