Regarding Atun-Shei, I think
this article about eunuchs was posted somewhere on this website before. Here are the best parts.
Eunuchs are generally represented as being vindictive and revengeful in disposition; this, if true, cannot be wondered at, for if they have been made eunuchs in their childhood, and against their own inclination, the injustice and barbarity perpetrated on them, as they grow up and fully perceive its greatness, must naturally rankle in their minds and tend to breed and develop all those vices for which we give them credit. On the other hand, should they have arrived at a period of adolescence, and have enjoyed intercourse with the opposite sex previous to castration or mutilation--either with or without their own consent--no punishment can be conceived more horrible than that which they daily and hourly endure--that of seeing women in their most abandoned moments, and knowing at the same time they have for ever lost their virility, and consequently, all power of the greatest enjoyment in life. They may beg and are, at the time, physically dead to all feeling of sensual pleasure, but it is impossible their minds and memories can be dead or oblivious of what
had been or might
still have been theirs, but for their mutilation. Those, therefore, who have indulged in sexual intercourse previous to castration, must feel the loss of their virility much more keenly than those who have been made eunuchs before they felt or experienced those mysterious workings of nature which accompany the adolescence of both sexes; and this also would tend to embitter and envenom all their after lives, and fill them with but ill-concealed envy and hate.

All eunuchs, when they are emasculated, lose their natural voices, those who underwent the operation when children can scarcely be distinguished from young women by the voice; while those who had the operation performed on them after arrived at maturity speak in a cracked falsetto--as a Billingsgate fish-fag might. In fact, there is something grotesque--if I may be allowed the expression--in their voices, not by any means pleasant to listen to.
...
Emasculation seems to take all manhood away from eunuchs; they age rapidly, looking sixty when only forty; they are like children; will burst into tears at a trifle, or give away to ungovernable rage for what another person would scarcely notice, and are as quickly pacified as they are to become angry. They are not by any means bloodthirsty--as eunuchs are usually represented to be--but exactly the reverse, being harmless and conciliating in manner, as if they sought to ingratiate themselves with those stronger than they are, by confessing--in their fawning demeanor--their own weakness and inferiority.
