SVT News has previously told about Harry Skärlund who in his teens watched porn several hours every day. He believes that he was abusing porn and he also noticed that his porn viewing had physical consequences.

- When you look at porn, no one is there to judge you, but with another person it becomes a completely different thing. I was so nervous, much because of the porn watching, that I couldn't even "get it".

"Have swallowed it with holes and hair"

At youth clinics, it is noticed that questions about whether there is any connection between porn and impotence are becoming more common.

- It is especially noticeable when we are in classes to talk to them, that you get several questions about it. They wonder if porn can be harmful and what happens when you look at porn, says Jessica Sunesson is the midwife and chair of the Swedish Youth Reception Association.

Fox Foxhage is the curator at the Stockholm schools youth reception. He says that he meets young guys who assume that porn causes impotence - something they call "porn rime". That, although there is no research to suggest that there is a direct relationship between pornography and potency problems.

- Some young guys have bought it with holes and hair. It comes to me and says that they have the porn tube potential. But there is nothing called porrimpotence. The problem of impotence has always been with some young people, but where you think it comes from has got a new source in the porn.

"Do no good"

Today, Harry Skärlund lectures on pornography and his former porn consumption. He believes that when it comes to young people's power problems, it is a lot about nervousness, but thinks it is important to get guys to talk about their porn viewing.

- I am convinced that porn does no good. It doesn't do these guys any good.
