AHAHAHAH Well I wasn't expecting this, but allow me! (Note that English is not my first language so if anything at the end of my explanation isn't clear, you can ask as many questions as you wish!)
Alright, let's analyze it through a few perspectives
I'll start by saying that little of our sexual preferences isn't influenced by something else in our psyche
And that's why I said you guys might not like it and it's also possible that you yourself wouldn't know the reason, it being a subconscious thing;
There's more than one type of pretty boy seme (I dare you to drink a shot for each time this freaking term will me repeated in the text.)
-There's the normal pretty boy seme, as in the one who's not a crazy yandere but just someone with preferences
-There's the crazy yandere (for me, I dig yandere semes damn)
-Rare but still present, the Tsundere pretty boy seme
But mostly, the pretty boy seme is a trope based off the seme most probably being younger than the uke, or rarely being older but not looking like it
And the seme being kinda
Possessive? Yeah, that's probably it
A sex expert, possessive, aggressive in a sexy way
Or a sadist/dom, so more collected and calculative
But what does all of this suggest in our psyche?
The simplest thing is that we like Surprises
It's also a kink in itself, some people can get off on something taking a turn they didn't expect or even didn't want
So the gap that's created with a pretty boy, as pretty is usually associated to females, being Seme and perhaps also cold instead of kind and everything, is something to note
But this is just the tip of the iceberg, so let's get deep, sweeties!
I'll give an explanation for the "Vanilla" pretty boy seme and one for the Dom/Sadist/BDSM pretty boy seme
So see which one belongs to you most
The Vanilla Pretty boy seme
This one is actually pretty simple but still might not be accepted easily
Since pretty boy semes are usually younger than the uke or just young looking, but they always refer to the "Younger" thing
Some people experience certain things in life
Scary stuff, frequent stuff, but it doesn't matter how often something happen in the world, what matters is how those experiences affect the person
How traumatic those experiences could be to them
So we need to respect this, even when the big problem they're dealing or have dealt with is something we don't see as a big problem at all
Now we have this clarified
The kind of trauma I'm referring to is usually social
And involves your peers probably, sometimes even siblings if they're your age or older
So something like bullying in general, school bullying, family bullying
It depends on who you are of course, but some people are affected by these kinds of social issue in a way that makes them subconsciously (sometimes consciously tho) afraid of their peers or of older people
Here's one other part you might not like: when this happens, the person of interest might end up with the need to
Err
Feel superior, I guess? To the younger person
Why? Because being superior to someone makes you feel like they can't hurt you
'Cause if a cute thing threatens you, it looks like a kitten baring it's tiny fangs, doesn't it?
It might not look like superiority/inferiority thing
But unfortunately, it is
Although the reason is the person trying to protect themselves
Now, on to the next step of this ladder that goes down the whole iceberg
Don't worry, as long as I'm here, I won't let you dear readers drown! That's why I'm here for questions and all
Back to the topic
So that's good
Now here's the thing
If you're thinking "but not all of those works have a bullying past of the uke" or something like that, always remember that not all authors are psychologists of course, so when this kind of thing is shown in their work, it might be 'cause it's their own kink, so most probably they don't know the reason for it, or they're doing fanservice
Since we might perceive authors as omniscient when we read, but they aren't
In the case of the Vanilla Pretty boy seme, the uke would approach him for various reasons
For example, he thinks he's a girl
Or He thinks he's straight but confused as to why he likes this boy
Or even they've been friends for a long time
Either way, the Uke probably thinks the other is harmless
Infact often these stories are about a Seme that turns into an Uke
'Cause if the uke approaches our pretty boy seme for sex, he probably expects him to be a Bottom, doesn't he?
Taking in what we have previously said: the Uke is afraid or more cautious when he's with his peers or senpais, the Uke tends to often think "he's short, thin and pretty, he's harmless!" So that he can feel superior and perhaps wanting to protect him, such is the harmlessness he feels coming out of our Pretty Boy
HAHAHA Well you guys know how this ends, don't you
You'd like to be in the uke's place
But why? Why isn't the uke just gonna top him as he sometimes would like?
Well, let's not forget yaoi is full of stereotypes etc., but other than the reversible couples there's also those times where the Seme approaches the pretty boy uke for the same reasons the Uke in our story would
But nothing changes in that case, unless the author makes it so that said Seme becomes less afraid of his peers and stuff
But the pretty boy seme trope is more of the Direct Therapy you could say
Where you're suddenly faced with your trauma and must survive
'Cause the uke, trying to escape his fears by approaching harmless boys, is actually closing himself in his bubble, which he should come out from
But when the Generalization no longer works, when the Uke sees how the Pretty Boy can still behave like a Seme and still be pretty, that's when he's faced with reality
How fragile was actually his strategy to avoid getting hurt
That not every older, if the pretty boy reveals to be older, or peer person must be a foe, someone that wants so bully you
Eheh remember we're still talking about the Vanilla type
So the Uke with the Vanilla pretty boy seme is able to realize that THAT was what he needed, although he didn't want it
'Cause in life, most often it's what we don't wish for that might be what will actually help us and make us happy
Your ideal type might not be what you need
Just like the Uke's type was probably pretty boys for them to be bottoms
Nicely done our Vanilla Pretty Boy seme, now it's time for my favourite one!
Yeah man, Vanilla's boooring (jk, or am I?)
So this one was chill, something you wouldn't wanna hear perhaps, but still chill
This next one might not be as chill eheh
(Note: since this walltext is probably long enough and you darlings might want to kill me for its lenght, I'm not going to explain the possible scenarios of seme's past for him to be a Sadist/Dom etc. - just so you know, even if I find it unappealing sexually, in real life reversible is what cuts a healthy psyche 'cause you don't try the other out of fear)
Alright then, this Seme!
Now now, who doesn't like a Wolf in sheep's clothing? I know you do ;3
THIS Pretty boy seme!
Why do we like him?
There are many ways one can react to those social traumas I spoke of earlier
One can be to need cuddles, like the Vanilla one
Another one can be to become themselves a perpetrator, one can even not be affected and there's the one we're talking about: the one who wants pain.
When you receive pain, you don't actually quite get how it works
Perhaps you feel guilty
And you need to punish that guilt away
(That's a sub for you, you're welcome)
Perhaps the Uke's not aware he's a sub/masochist himself
Remember there's also the Brat in BDSM, not to forget!
So, same conditions as before, the Uke approaches the Seme, thinking him to be a sheep
He probably wants to top him
But BOOM! He gets tied down and fucked senselessly
If you thought "sexy", we might be in the same boat, buddy
So, here too the thing of Not Expecting is important
More than before
'Cause this is the complete opposite of appearance
And this calls for another factor: the unconscious or conscious (again depends on the awareness of the person) to be Dominated by a YOUNGER person
Dominated, abused, humiliated, bullied by someone who looks Harmless
Now, we're in the dept (at least as deep as I'm getting with this, let's say I'm not considering more extreme examples, perhaps related to actual dangerous insanity, murder and stuff)
Remember the traumas of the Uke
Remember his fear
Just like the Vanilla couple, our Uke here too subconsciously looks down on the Seme and also wants to be embraced
But not in a soft way, instead he wants it in a rough way
To be bullied
But of course, after care is important in every BDSM relationship
Everything wants love and affection too and everyone deserves it <3
He's afraid but it might be important for him when he finds out the sheep who looked harmless was actually a strong wolf
Damn I love it when pretty boy semes are strong and can even LIFT the tough ukes TwT
So sexy
Alright sorry for that display of shamelessness, Ahem
We were saying
So here the Fear Uke has of peers and stuff clashes with the sexual excitement that receiving that pain and humiliation can give
It's a different kind of redemption for the uke
He craves it
He craves for someone that he wants to be harmless to NOT be harmless at all
To be wrecked
The kink of having your pride or trust broken in this way, which might or might not be a major way for it to happen
Here the superiority complex is you wanting to be inferior at its finest, as the uke
You get now what I meant? This is the psychological reason for liking a pretty boy seme so much: they look harmless but we don't want them to be 'cause it's sexy if they actually aren't
The kink of being deceived
For these reasons
Social traumas can be a hassle to get through
You self esteem lowers, your fear and trust issues increase
But when you start avoiding, that's the End
The End of your healthy self
Avoiding what you think might hurt you, be it hanging out with friends or doing other stuff that involves social relations, will make the problem worse :(
And I'm talking out of experience
Please guys, don't think that you can't trust anyone, don't lose your Trust in the world :c
Be honest to yourselves
If you can, do seek help from a professional
You don't need to be a crazed shit to need a Psychologist
Everyone does, I'd really recommend it to ANYONE, even the sanest person I know <3
And remember,
In this big boat of perverts with strange kinks,
You're not alone
idk if its just me but i loveee pretty boy tops
