With respect to Jewesses and the powerful, I think the cause of this connection is the Esther Syndrome, the idea that the young Jewess has it within her thighs the power to twist the mind of the powerful goy ruler to the benefit of the Jewish community. (In fact, I read just such a favorable interpretation of the doings of young Monica Lewinsky.) And the origin of this notion is, of course, Purim. Jewish girls are socialized to look with favor upon the deeds of the courtesan Esther (no queen she), who saves the jews with her moist sexual favors, all under the approving gaze of her Uncle Mordechai. As the Homosexual is merely a stunted man cursed with the mind of a girl, it is easy to see why a young jewish homosexual would identify with Esther and present himself in similar terms.
I think this answers your question completely and fully.
