That isn’t engaging with my comment. I have no idea what “psychoanalysis” reading you’ve done.
It sounds like you are looking for some sort of ideal Knowing of oneself. Of course that seems an impossible dream. But that doesn’t mean we can’t develop a deep understanding of ourselves, becoming familiar with many of the factors that make us who we are.
Of course, I don’t know everything about myself, and life shows me plenty of times I’m mistaken or fool myself, and indeed didn’t know myself as well as I thought. That’s why we seek adventure and experience, to test the mettle. For me, in the end what matters is being honest with oneself. Live and learn from the screw ups and bang ups, as much as from the victories.
You demand the sort of technical understanding and control a dam builder requires. That won’t help you understand your chaotic self and the even more chaotic river of life you’re stuck in. You need the understanding and “control” of kayakers. Feeling the current and finding your line through the bends and rapids, and controlling your flimsy craft.
There are no ideals, it’s pretty much all about close enough, timing and location. I’ve dedicated my entire life, since before kindergarten to figuring out who the heck I was, and can say with honesty, seek and ye shall find. And it’s worth every moment of the struggle.
an aside of sorts . . . . . . .
“There are no ideals” well there I go, talk about contradiction, eh?
Thinking on it right now, I have to admit, my life is build upon a few ideals, ideals I could spell out.
The secret I learned is believing in your ideal, striving for them, and when you fail, okay, get back on that horse and do better next time. You know take it seriously, but we don’t need to be wearing horsehair shirts. Which is my impression of what you like doing to yourself.
Your starting point seems worrying about what everyone else is writing - My philosophy and intellectual starting point was figuring out myself, I also became very interested in Earth and her evolution.
Now I appreciate the importance of a deep biological understand of the human material creature that creates my mind.
Once I figured that out, everything started making much more sense. From our individual evolutionary biological heritage, we can realistically start understanding why we are as we are, our impulses and behaviors and attitudes started making sense and falling into a comprehendible impression, like it never could before.
I have come to see how much of the rest of philosophy/theology is simply another expression of humanity’s utter self-absorption and self-serving nature. Sure its practitioners have created some wonderful and useful understanding, ideas, and endless intellectual entertainment, still in the end haven’t been much help in grappling with our biological reality, always missing the mark, too busy shadow boxing with God, and competing egos.
“Unmediated” what are you expecting?
Think this through, you are an evolved thinking animal in a huge world.
Your only connection to that world is your body/brain, everything, I mean everything that enters your mind, has been meditated all over the place. There’s simply no other way for a physical material world of creatures to operate.
Of course, I don’t connect with my lover’s inner mind. Our bodies connect and create a unique moment, that is owned by both of us, and impossible without both. Whether a single special encounter or something that develops into ever deeper and long lasting connection.
What do you expect of your ideal “direct” experience?
Can you imagine what it would look like, or feel like?
So is the problem that you simply haven’t ever found some other person that resonated with you?
That’s a tough one.
We all need some real human company and touch, even if it’s just holding hands, a voice to listen to and a set of eyes and ears waiting to hear what you have to say.
It’s been said we get out of life what we put into it.
Hmmm.
Take a look at imagery of what’s going on inside your body, at any level, look at some time-lapse videos of city sidewalks, or harbors, city traffic, or nature scenes of every variety.
We have a water based body, and live on a water planet - denying the fluidity of our lives, seems an act of turning your back on the physical world where the answers are. Well, the mysteries are out there too. I’m okay with that, I don’t have the hubris to believe nature owes me an answer to my every whim.
Yes of course. Still you are part of the crowd. 
Okay fair enough, that is all we have. But to say “no direct knowledge” is an over-reach that ignores human biology.
Resonance.
Our bodies project what we are feeling - an attuned body ought to be able to sense those vibes in another person.
Okay, we still we don’t “Know” each other’s minds, and if it’s good, everyone’s “the best lover ever”, at least for that moment. That’s simply how it is. We are simply humans, not divine creations. Why do you make it seem like a deal breaker or nature playing dirty?
inthedarkness you’ve got plenty of reasonable complaints/questions, still you’re after idealism, and that seems hopeless, nothing about us is ideal.
