The newly conquered is an observer, which idolizes the Narcissist. Moreover, the act of conquering and subordinating is at its apex in the sexual encounter. This is nectar to the Narcissist. The distinction between passive and active sexual partners is mechanical, false, superfluous and superficial. AIDS is no longer the reserve of homosexuals.
Narcissists are, at times, suicidal.
I know of no heterosexual who would use his sexual preferences to define himself almost fully. Homosexuality has been inflated to the level of a sub-culture, a separate psychology, or a myth. This is typical of persecuted minorities. However, it does have a feedback influence on the individual. Preoccupation with body and sex would tend to narrow down the types of Narcissism available to homosexuals.
