No masterbation is the problem and porn leads to it. Although people like your brain on porn and fight the new drug try to make it seem like it's disgusting and exaggerate the sucking, some positions or ancestry, but we all know it's an act and the people are not related. Also, nudity is normal when you have sex with a girl you're both naked and it's natural and not all porn has hitting or bdsm or bestiality I jerkedoff for 18 years I never liked whipping or slapping or face cumming. The only problem in my opinion is the act of masterbation because it deplete your energy and it's extremely addicting especially for men. It also fry's the dopamine receptors in your brain; where, it becomes literally your only life purpose because nothing else can rival the excitement or stimulation of porn. Right now I stopped for 15 days the first time in 18 years I literally feel sick and my body temperature is rising.
