The funny thing about a couple of Narc men I have known- They are actually kind of unkempt and sloppy. That is the cerebral side of Narcissism.
They don't really like sex, or intimacy they prefer porn and masturbation. They want to seem like they are knowledgeable and worldly yet are unsophisticated and unintelligent.

The cerebral interested in appearing like an intellectual God. I also believe that they are usually ashamed of their homosexual feelings.

The Somatic Naricissists are more interested in conquering sexually. They are closer to HPD. They want to appear attractive and adored.

This is just my humble opinion.
