Look, this is the section of that article:
"Many of these same emotional states (anxiety, shame, shock, surprise) not only elevate dopamine, but each can also boost stress hormones & neurotransmitters (norepinephrine, epinephrine, cortisol). These stress neurochemicals increase excitement while amplifying dopamine?s already powerful effects. Over time a porn user?s brain can mistake feelings of anxiety or fear for feelings of sexual arousal. This helps explain why some porn users escalate into ever more shocking or anxiety invoking porn ? as they need that extra neurochemical jolt just to become sexually aroused, or to orgasm."
Drinking increases my anxiety hence the above is true. If you get anxiety from drinking, maybe you should stop.
