Dr Gomathi Sitharthan, a professor of sexual health at the University of Sydney, said the unlimited access to porn has warped young people’s views of sex and relationships and has long-term effects.

“If a girl seems to like being treated roughly, has sex with five guys, has sex with the pool guy or the pizza delivery fellow five seconds after they meet - inform them that it only happens in movies. This is not the norm,” News.com.au quoted Sitharthan as saying.
