Other studies disagree as well too.
These excerpts from [1] sum it up kinda well (I recommend reading the full article, it makes a few additional points not listed here):
"“My biggest concern regarding the scientific study of porn is that a noticeable subset of researchers come at these issues with a focus on harm in their minds. They try to establish ways to confirm that porn is causing whatever harm they already believe exists,” he says. “The field needs more people who are willing to look at the data and leave aside their politics and their issues.”" [1]
"Voon says. “What we do know with porn is that there are some patterns that are consistent with an addiction – but some that are not. We need much larger epidemiological studies to know for sure.”" [1]
"A meta-analysis – a study of studies – published by Malamuth in 2009 found that hundreds of papers from the 1980s to 2008 were fairly consistent in linking high rates of porn viewing with violent ideas and behaviour. But here’s the caveat: not all men respond to porn in the same way." [1]
"For most men, consuming porn will not cause them to view women differently. But in those who already are predisposed to hold sexist views or to behave in an aggressive fashion, porn can exacerbate pre-existing and dangerous propensities. In this way, it’s just like any other drug."
"Alcohol, for example, is in many ways comparable to porn because it is ubiquitous, socially acceptable and legal."
“For some people, alcohol can truly ruin their lives,” explains Malamuth. “But for others it can be mildly positive, such as providing stress relief or enhancing their sex lives. It depends on the cultural context – and the individual.”
"The field is riddled with misconceptions and biases that are not supported by the data, she says."
"Despite concerns that porn can decrease libido and lead to impotence due to ‘tolerance’ and ‘desensitisation’, research published by Prause in the journal Sexual Medicine in 2015 shows these worries to be unfounded."
"“The most well-replicated and concerning harm is reinforcing rape myths in men who already believe them,” says Prause. Such that if you take a woman on a date, she owes you sex. Or that women secretly want to be coerced into sex."
