PostUllrich's Biography of Hitler; Hitler's Sexuality (Leo Goldberger, USA, 10/07/16 1:32 am)
Bringing to bear the factual history of Hitler's complex personality is actually the strength of the Ullrich biography. The prurient interest in Hitler's testicles (which the biopsy determined were in fact normal, according to Ulrich's evidential sources) is obviously as silly as the focus on the size of Trump's hands!
In Ullrich's chapter 10 (pp. 267-280) you might find an impressive account of Hitler's manifold relationships with women, both sexual and non-sexual, that does cast an illuminating light on his being--beside simply calling him "psychotic," whatever that rather broad diagnostic term may mean to you.
JE comments: Perhaps these matters shed valuable light, perhaps not--but I recall it once being a commonly accepted historical fact that Hitler died a virgin. This could be interpreted in two diametrically opposed ways: either that he was completely dysfunctional in the sexual sense, which would explain his diabolical actions, or else he was so dedicated to the German nation that he had no use for distractions or pleasures of the flesh.
