I would argue everything in moderation but it's undeniable the adverse influence constant porn consumption has on the male psyche..biggest example is that a lot of men become too attached to the men playing in the roles subconsciously, the fascination of the act of penetration or any other sex act that showcases an example of sexual dominance is a Pandora's box.
Becoming obsessed over the penis that's committing the act, controlling the female...making her supposedly submit. In the end, some men become infatuated more so with the apparatus by itself or how it is used in during intercourse. This can for the most part, make up for the feeling of inadequacy or the inability to attract women as desired due to penis envy or inability to sexually engage women as desired. JBO is a great example of this where dudes talk about the girth of dikks, expressing admiration for them in certain cases or the amount of ejaculate they can create.
