Watching porn is not unhealthy, but a study has recently warned that men, who regularly watch porn, are not sexually satisfied in their relationship with their partner and are more likely to suffer erectile dysfunction.
It suggested males addicted to adult movies become disinterested in sex with their partners because their 'sexual tolerance is higher'.
Erectile dysfunction is an inability to get or keep an erection firm enough to have sexual intercourse. It's also sometimes referred to as impotence.
Porn is often blamed for turning men off sex with their partners, but one in five men watch X-rated films to avoid intimacy, it was found.
It follows a recent study that discovered men who, regularly watch porn, are more likely to become disinterested in sex with their partners.
Dr David Ley, a clinical psychologist specialising in sexual problems, said that men use masturbation to compensate for lack of sexual satisfaction in relationships.
As this sexual behaviour is often accompanied by viewing pornography, it can be easily misunderstood,' he told The Sun.
A team from Los Angeles, California, studied 335 men in relationships.
The findings revealed that 22 percent reported of viewing porn to having sex with their partner.
They also found that 28 percent of respondents said that they opted for masturbation over intercourse.
The males, who preferred watching porn or masturbating rather than intimacy with their partner, reported feeling much less happy in their relationships.
The results also indicated that males, who opted for masturbation over sex, also reported more difficulty maintaining erections.
