The problem here is that causality (on the male side) could be inverted. There's a relationship between dissatisfaction with sex and usage of porn, but we can't tell which causes the other. It makes logical sense either way: A) Men who are having less sex with their partner use porn more. or B) Men who use porn more stop having as much sex with their partner. Age is another factor to consider. As men age, sex with a partner may become more anxiety-inducing or difficult.
