Robbins suggests that individuals in whom sadism predominates as a personality trait are likely to become homosexuals. Given the presence of such sadistic drives, men turn to other men for gratification because they are unable to exploit women as successfully as they can men. The homosexual 'marriage' is overvalued, because it affords the partners the opportunity to enslave and exploit each other and simultaneously to lose their own identities in the allencompassing relationship.

These conclusions and others were derived from the analysis of two homosexuals of utterly different personality make-up, but resembling each other in the prominence of the sadistic fantasies and the parallelism of their respective marriages.

The psychogenesis of the perverse strivings of the patients is not clarified in its details, and therefore Robbins's concern with weaknesses in the libido theory is not very convincing.
