T.E. Lawrence (of Arabia) discussed this also in his book "The Seven Pillars of Wisdom." So, it has some basis in historical fact as well, not just PhD pschyobabble. There is reference in the Qu'ran to not just the virgins in paradise, but also to beautiful young boys if you prefer or want both.
Interestingly when I was practicing medicine I ran across this same mindset in the newly immigrant Hispanic community, that the male who penetrated was not homosexual, just the recipient. This is another macho culture, where many women were untouchable, guarded by duenas, and others would keep their virginity by allowing anal intercourse but not vaginal.
The world is weird.
Original camels had flat backs. The hump(s) is/are cuased by............. ;-)
Is that why they spit, too?
Camels are so mean because they, along with Giraffes and CATS, locomote without doing CROSSCRAWLS ...which leaves them with "Two Minds". Ask a Cat owner to explain the Feline Unintegrated states of consciousness.
As to Anal Sex with men, which I presume this article deals, the act of being penetrated DOES emasculate, for the following reason...the Anus has TWO sphincers, about 1/4 inch apart. But (no pun intended) each is under control of a different nervous system. The Voluntary Nervous System consciously relaxes during Anal Intercourse. That does NOT Psychologically castrate. The other Sphincter is under the control of the Involuntary Nervous system, which is wired into the deepest parts of the personality. This Sphinter resists Penetration because at the Unconscious level, to yield is to litterally CHANGE IDENTITIES.
But under the intense pressure of a fully erect penis, after a time, it physically gives way, and the victim almost always experiences incredible, ineffiable, Feminizing emotions, which are cemented in place by a corresponding flood of Brain Endorphins triggered by the pain of resisting and yielding.
The BEST that such a "receiving end" male can hope for is a Bi Sexual personality, at worst he is totally emasculated.
The RAGE accompaning this is not to be believed!!!
No wonder Mohammed Atta left instructions that no women be allowed to even visit his grave!!!
