Pornography consumption makes you lazy. We are only able to be happy a set amount of time during any day. If we jack up our dopamine by masturbating to pornography we will be less inclined to make meaningful accomplishments that will benefit our goals for the future. (Masturbating to pornography gives you the highest natural dopamine high possible). Our brain will also make less dopamine for our future accomplishments.
Pornography also leads to a reduction in brain gray matter volume, so the meme of the brain dead masturbating wojack is very accurate. Here is a excerpt from a study on pornography use and gray matter: "Results We found a significant negative association between reported pornography hours per week and gray matter volume in the right caudate (P<.001, corrected for multiple comparisons) as well as with functional activity during a sexual cue–reactivity paradigm in the left putamen (P<.001). Functional connectivity of the right caudate to the left dorsolateral prefrontal cortex was negatively associated with hours of pornography consumption."
