[...] that tendency which is sometimes found, more especially perhaps in women, for the sexual emotions to be absorbed, and often entirely lost in self-admiration. This narcissus-like tendency, of which the normal germ in women is symbolized by the mirror, is found in minor degree in some feminine-minded men, but seems to be very rarely found in men apart from sexual attraction for other persons, to which attraction it is, of course, normally subservient. But occasionally in women it appears to exist by itself, to the exclusion of any attraction for other persons.Ellis, H.
