I answered a few questions for HIVequal.org about an article I recently published in the scientific journal AIDS & Behavior. They used my responses and wrote a great article titled "Watching Bareback Porn Linked to Sexual Risk Taking, Study". In short, our study found support for a link between viewing bareback pornography (porn that doesn't feature condom use for anal sex) and engagement in actual condomless anal sex among viewers.
Before you jump to any conclusions on what we found or what we think the findings mean, take a look at the article HIVequals wrote. Although there seems to be a link here, I don't believe the issue is that porn is teaching people about sex, it's that there are very few places where people can go to learn about sex, thus making porn a viable option. If we want people to stop learning about what normative sexual behavior is from porn then we need to provide people with accurate and adequate sexual education.
Vice.com recently wrote an article titled Does Gay Porn Make You Hate Your Body? This is a review of the article Thomas recently published in the scientific journal Archives of Sexual Behavior titled Viewing Sexually Explicit Media and Its Association with Mental Health Among Gay and Bisexual Men Across the US. A link to both the review via Vice and the journal article are below.
