"some", not all.
Many believe that using kiddie porn raises the probability that a person will in fact be affected by it & will engage in sexual contact with children.

Can child porn users be treated?

He says his obsession meant he was looking at all types of images which were becoming more and more extreme - and the internet enabled him to do this.
Mr Findlater said the majority of men that he had dealt with had started looking at images in this way.
"What they've done may never develop into a sexual interest. The majority of men would say they were viewing adult pornography and then started looking at things on the edge and that's how they ended up with it."
John said he "didn't appreciate what happened to the children for them to be in that position".
"The children are portrayed often smiling and happy and a lot of the images are them posing and I did not consider the surrounding circumstances.

'Abuse rings'
Dr Jon Bird, from the National Association for People Abused in Childhood (Napac) who was himself abused when he was a child, said producers of these types of images blank out the surroundings to hide clues and minimise the risk of discovery by authorities.
He said it also made it easier for the viewer to see the child as an object, and it was easy to make a child smile with sweets or flattery.
"It is very common for users of pornography to see images that they find stimulating and not think of the people in the images as individuals with human rights and feelings."
"It is like being raped again and again every day," said Dr Bird.
"To know that perverts are looking at these images adds to the difficulty of recovery which can last long into adult life.
"Some survivors know that the images are passed around and traded in abuse rings.
"This fact can also be used by perpetrators to make it harder for survivors to go to the police or seek therapeutic help because the perpetrators threaten to make the images more public and put the survivor's name in the public domain as well as the images."
And once the images start to be distributed on the internet, there is no way of ever being sure they have been completely removed.
"This leads to a permanent state of worry about the possibility of being recognised or associated with having been abused," added Dr Bird....
