Customs Crackdown On Child Sex Dolls As Expert Warns They 'Feed' Paedophiles

As customs crack down on the importation of child sex dolls into Australia an expert warns the dolls "feed deviant sexual fantasies" instead of helping relieve paedophiles from offending as a Japanese manufacturer claims.

Up to 18 attempted importations of child sex dolls have been stopped by Border Force since 2013, Fairfax revealed on Sunday, while the dolls remain prohibited from importation into the country.

Japanese child sex doll manufacturer, Shin Takagi, is a self-proclaimed paedophile who has never acted on his urges. Takagi said the dolls help paedophiles relieve their sexual urges without harming children.

The dolls sold by Takagi's company, Trottla, resemble very young girls -- some with lingerie and movable joints.

"We should accept that there is no way to change someone's fetishes," Takagi told The Atlantic in January.

"I am helping people express their desires, legally and ethically. It's not worth living if you have to live with repressed desire."

Clinical and Forensic Psychologist Dr Katie Seidler, who rehabilitates child sex offenders and paedophiles, told The Huffington Post Australia the dolls don't relieve paedophiles, but encourage their sexual desires instead.

"Using these kind of sex dolls is not at all helpful in managing paedophilic tendencies," Seidler said.

"All they do is feed deviant sexual fantasies that are reinforced through the process of masturbation and ejaculation, thus making the degree of arousal stronger and ultimately contributing to a potential desire to act out in 'real life' rather than through the fantasy of a doll."

This year more than 60,000 people have signed a petition to ban the sale and importation of child sex dolls in Australia, and "ideally" globally.

The petition calls for Queensland Premier Annastacia Palaszczuk to make change, despite the dolls counting as child exploitation material already.

Importation fines include up to 10 years' imprisonment and $450,000.
