His deep depression also explains (at least partially) why Hitler had no relationships whatsoever (neither platonic nor romantic, let alone sexual). Which was quite unexpected, because Adolf Hitler was naturally charismatic, a captivating speaker and had an excellent taste in clothes and thus possessed the key qualities that attract scores of women.
They actually did – during his visits to the State Opera in Vienna he was approached (quite possibly, on a regular basis) by young women who wanted to flirt with him and to “know him better”, but he reacted to these attempts with cold indifference.
Which was quite strange, because he grew up in a normal and (according to his sister Paula) quite happy family. He loved his mother dearly (and she loved) him; was deeply emotionally attached to her; had close and loving emotional relationships with his sister (and with his aunt who financed his stay in Vienna) so obviously he had no problem establishing and maintaining healthy emotional relationships with women.
There is not a shred of evidence that even hinted at his homosexuality or any sexual deviation or perversion (e.g. sadomasochism). Biologically he was absolutely normal (as was attested by the doctors who closely examined him when he was called for duty into the Austro-Hungarian army).
However, it appears that his depression was only one of the driving forces between his essentially monastic attitudes towards women. Not just celibate, but genuinely monastic.
The first (and probably the initial) driving force was actually about monasticism. When he was ten years old, his father sent him to the local Catholic monastery at Lambach to develop his singing abilities (which he reportedly had).
25 years later he wrote in Mein Kampf:
“I was placed in a very favorable position to be emotionally impressed again and again by the magnificent splendor of ecclesiastical ceremonial”
“What could be more natural for me than to look upon the Abbot as representing the highest human ideal worth striving for?”
It can be inferred from this statement that for some time in his childhood, Adolf Hitler seriously considered becoming a monk and subsequently rising to the position of an Abbot of a major monastery.
Predictably, he did not pursue this objective, but it is possible (quite likely, actually) that he got so drawn to the monastic lifestyle that he (at least subconsciously) that he decided to emulate it as much as possible in his life. Which, obviously, was to remain completely secular.
First and foremost, emulate the monastic attitude towards relationships with women. Which (of any kind) were strictly prohibited by austere rules of any Catholic monastery.
This monastic attitude towards women was further reinforced by the moral code preached by his hero and his role model von Schönerer. This code required celibacy until the 25th birthday and, interestingly enough, called for abstinence from eating meat and drinking alcohol (seen as stimulants to sexual activity) – the dietary habits that Adolf Hitler kept for the rest of his life.
Obviously, visiting prostitutes or any other “sexual services establishments” was out of the question. Not just for moral reasons, but to “uphold the strength and purity of the Germanic race” (prostitutes should be left to clients of ‘inferior’ races).
Von Schönerer was not only an ardent anti-Semite, but a no less ardent misogynist. No wonder Adolf Hitler developed strong misogynistic beliefs and attitudes. He had very little (if any) respect for the female sex (considering his mother and sister a rare exception).
Actually, von Schönerer moral code was not that much different from the “official” moral code of the Dual Monarchy. However, while few took this moral code seriously (the prevailing culture widely expected to visit prostitutes while publicly upholding a strict moral codex), Adolf Hitler was among those few.
He may have been possessed many unpleasant qualities (and he did), but he was definitely no hypocrite. He walked what he talked and practiced what he preached. He sincerely believed in the necessity of following the moral code preached by von Schönerer (and the Imperial propaganda) so he strictly followed it.
It is also most likely that Hitler was genuinely afraid of women. More specifically, of getting into a close emotional relationship with a women and of a female sexuality.
He once had a very emotionally close long-term relationship with the woman (with his mother) which was abruptly (and brutally) terminated by her death. It caused him such an excruciating pain that he had no desire to go through this experience again for any reason (e.g., breakup).
And, at least subconsciously, he felt that he was destined for a great and glorious Mission. So he was (correctly) afraid that the emotional and sexual power of a woman will drag him into (and keep him in) a relationship and family that would prevent him from accomplishing this Mission.
Anyway, it would be safe to say that that by the time he left Vienna at the age of twenty-four Hitler had had no sexual experience whatsoever. Unfortunately, he did not pursue any significant project that he could channel these energies into (it is called sublimation or transmutation).
Consequently, his repressed sexual energies only made his psychological and emotional problems (namely, his bipolar depression) worse.
