Narcissists are either cerebral or somatic. In other words, they either generate their Narcissistic Supply by applying their bodies or by applying their minds.

The somatic narcissist flaunts his sexual conquests, parades his possessions, exhibits his muscles, brags about his physical aesthetics or sexual prowess or exploits, is often a health freak and a hypochondriac. The cerebral narcissist is a know-it-all, haughty and intelligent "computer". He uses his awesome intellect, or knowledge (real or pretended) to secure adoration, adulation and admiration. To him, his body and its maintenance are a burden and a distraction.

Both types are auto-erotic (psychosexually in love with themselves, with their bodies and with their brain). Both types prefer masturbation to adult, mature, interactive, multi-dimensional and emotion-laden sex.

The cerebral narcissist is often celibate (even when he has a girlfriend or a spouse). He prefers pornography and sexual auto-stimulation to the real thing. The cerebral narcissist is sometimes a latent (hidden, not yet outed) homosexual.

The somatic narcissist uses other people's bodies to masturbate. Sex with him - pyrotechnics and acrobatics aside - is likely to be an impersonal and emotionally alienating and draining experience. The partner is often treated as an object, an extension of the somatic narcissist, a toy, a warm and pulsating vibrator.

It is a mistake to assume type-constancy. In other words, all narcissists are BOTH cerebral and somatic. In each narcissist, one of the types is dominant. So, the narcissist is either OVERWHELMINGLY cerebral - or DOMINANTLY somatic. But the other type, the recessive (manifested less frequently) type, is there. It is lurking, waiting to erupt.

The narcissist swings between his dominant type and his recessive type. The latter is expressed mainly as a result of a major narcissistic injury or life crisis.
