Certainly. I'll answer it as concisely as possible.
#1: Nekos are usually cutesy, innocent, etc etc. This is attractive to a lot of men, so it's not surprising that Nekos are often a staple request, because they're a derivative of the all overpowering desire to take what is innocent and either protect it, in a caring and loving manner, or smother it, corrupt it, and twist it to one's own enjoyment.
#2: They're... Odd. To say the least. How to explain. There is a minor difference in how men and women perceive things, and imagine things, and conceptualize things. Men tend to embody themselves in the situation whilst women tend to play it out as a third party whom is merely observing the incident. This is why masculine culture often includes giving personifications to weapons or vehicles; they're extensions of a man's perspective of self when used repeatedly by said man.
How this ties in to your femboys comment is that when a man tries to imagine a feminine male they imagine
themselves as a feminine male subconsciously first, and
then, through conscious effort, imagine someone else in this position. Being that men identify themselves as masculine by an overwhelming majority, this is off-putting to say the least.
Now don't take this as the rule, there are exceptions as there are virtually no rules in psychology for how people behave (just suggestions and certain patterns that usually prove true), but this is the "golden standard" sort-to-speak, and if I had to take a guess, it's probably because of this.
#3: This can be chalked up to the
uncanny valley. Essentially speaking, the uncanny valley is the measuring stick by which we differentiate between three general states on a scaling level: Obviously not human with human characteristics, bizarre and jarring, and human.
The first state is something like... For example, Toy Story. The characters in the story are cartoon toys. They're obviously not human, yet they have human characteristics, which makes them relate-able, adorable, likable, even attractive to some people. This is why we find puppies and kittens and birds and ferrets and mice and all sorts of creatures and animals adorable; so long as they have some kind of human-like characteristic, like being cute, or apparently displaying emotions, or learning, or singing, or any measure of other qualities, we can forgive the obviously not human quality.
The second state, which is often where androids fall under, is the bizarre and jarring category. The category where it's just human-like enough to be not, not human, but it's still not human, so it becomes instantly jarring and disturbing to the mind. A zombie is an example of this: It's a dead human. It's not, not human, but it's not human. The brain doesn't know how to deal with this aside from sending signals of fear, being disturbed, and pretty much the opposite of being turned on.
The third state is where something is so human-like that we mistake it for being human, or it is actually straight up human. A fictional character written well enough can become this: So human-like, that they may as well be human despite being fictional.
The one major note to affix to this is that "your mileage may vary". That is, what is uncanny and disturbing to one person, may be just fine to another... But in general? The more human-like it is without being human (eg: Humanoid form, humanoid voice, humanoid emotions, humanoid desires, humanoid sexual contact, etc) the more likely it is to trigger the uncanny valley effect in some people if it is also explicitly not human (eg: AI).
Amusing fact: This is also why certain alien physical archetypes are
absolutely fucking gut wrenchingly terrifying to some people, like the classic tall E.T. if drawn right and left in the darkness for your imagination to fill in the details, or the alien from the aliens series of films (whose entire race is literally a series of metaphors about penises and rape). Now, again, this turns on some people, and that's perfectly fine, but for the majority of people? It's terrifying to think about.
It's also why we attribute humanoid shapes and forms with grotesque mutations to the vast majority of demons and daemons throughout classical fiction. Humanoids that are not human are the easiest things to scare us with.
#4: Because a lot of sex goes on here and a lot of people, while seeking to write out adult fictions, probably aren't comfortable with throwing it out onto the forums. There is a certain level of security when posting stories in PM's, nobody can see them.
#5: Vast number of reasons. Not first language, never studied English well, skirting the rules about minimum age to join the site, not giving enough of a damn to write well in the first place... The list goes on and on and on.
If anyone has any further questions feel free to ask.
