He reported opening multiple videos simultaneously and watching the most stimulating parts. When he became aware of his excessive use of pornography, he stopped viewing it completely, telling his interviewer he was afraid that if he viewed it to any extent he would find himself overusing it again. Sensitized learning involves an enhanced mesolimbic dopamine system response that results in attribution of potentially pathological levels of incentive salience to cue-evoked seeking of drugs and natural rewards [ , , ].

As part of the addictions portion of his history he was asked about gambling, Internet gaming and pornography addiction. For example, it provides no statistical results for the erectile function outcome measure in relation to Internet pornography use. Seok and Sohn added that the severity of sexual addiction directly correlated with cue-induced activation of the DLPFC and thalamus. Since returning from deployment, he reported continued masturbation one or more times per day using both Internet pornography and toy. To date, no other researchers have asked men with sexual difficulties to remove the variable of Internet pornography use in order to investigate whether it is contributing to their sexual difficulties. The marriages most negatively affected were those of men who were viewing pornography at the highest frequencies once a day or more. He reported that when he attempted to have sexual intercourse with his wife, he had difficulty achieving an erection and difficulty maintaining it long enough to orgasm.
