How a former GB Olympian curbed his porn problem - and the signs and steps to recovery

Former Team GB diver Freddie Woodward was a teenager when he realised he had a problem with porn.

"Every time I sat down to revise, all I wanted to do was open those sites," he revealed.

By age 12, he was regularly visiting what he calls "hardcore" sites. As his career progressed - which included representing his country in the Olympics - he was watching adult content several times a day.

Now aged 30, the Olympian has told the BBC how he eventually curbed his habit by shifting his mindset.

"You can't be the person who is trying to quit porn. You have to be someone who doesn't watch porn, and that takes a lot of work," he said.

So how can you spot when a porn habit has become unhealthy, and how can you tackle it?

Although it has become a common phrase, "porn addiction" is not an officially recognised condition in its own right.

"We know a lot of people have a problem with porn," explains sex and relationship psychotherapist Silva Neves, who says the matter has become more prevalent among clients at his private practice.
