Angela Gregory now asks those seeking help about their porn habits

Leading therapist says she has seen a surge in young men visit her clinic

Smartphones are to blame for making the material accessible anywhere

More young men than ever are seeking treatment for erectile dysfunction because of their addiction to online porn, an expert has warned.

Exposure to graphic images and films are desensitising men and leaving them unable to get aroused in the bedroom.

Smartphones and tablets which makes porn accessible anywhere are to blame for the condition, a leading psychosexual therapist believes.

Angela Gregory says she has seen a surge in young men attending her clinic at Nottingham University Hospital.

She told the BBC: 'What I've seen over the last 16 years, particularly the last five years, is an increase in the amount of younger men being referred.

'Our experience is that historically men that were referred to our clinic with problems with erectile dysfunction were older men whose issues were related to diabetes, MS, cardio vascular disease.

'These younger men do not have organic disease, they've already been tested by their GP and everything is fine.

'So one of the first assessment questions I'd always ask now is about pornography and masturbatory habit because that can be the cause of their issues about maintaining an erection with a partner.'

The issue was exposed by a new documentary by the BBC's Newsbeat called 'Brought up on Porn'.

Researchers spoke to a young man named only as 'Nick' who first started watching porn on a laptop aged 15.

Despite wanting to have sex with 'real world' partners, he was unable to because he was 'wired to porn'.

It wasn't long before Nick's own sexual health began to suffer - and he blamed porn.

Nick sought help from a doctor and eventually cured himself by going 100 days without watching porn.

He said: 'At my peak I was probably watching up to two hours of porn every day.

'What I was watching, it definitely got more extreme over a short period of time in my case.

'There was nothing that would give me a kick. Normal stuff didn't do anything any more, so I had to get more and more extreme material.'

'I found that when I was lying next to a girl a lot that I just wouldn't be horny at all, despite being really attracted to the girl and wanting to have sex with her.

'My libido came back with a vengeance and I met this girl and it was great.

'For the first time in ages I was able to flirt and within quite a short time I was able to have normal sex.'

According to a 2014 study in the Journal of Sexual Medicine, one out of every four new erectile dysfunction patients were under 40.

And a new study in the Behavioural Sciences Journal claims that online porn mirrors drug-like addiction qualities, leading to lowered sexual 'enjoyment' and diminished libido.
