Oh gosh, why do you write such long posts, you aint american are you ?
I'll try and answer:
sexy smile or aw-she's-happy smile? gestures can be sexy in themselves, but are you talking sexy as they are, or sexy through your specific associations with her?
and gestures aside, there is nothing you'd consider shallow or static about her body that you like? if you didn't know her and met her today (i am guessing you originally where friends), knowing nothing about her, you would experience no sexual attraction towards her whatsoever?
Think I can answer that with one sentence: I met her on the internet. I chatted with her for a good four weeks before we met the first time. In that time I only had a picture of her but I eminently fell in love with her way of thinking back then. I have always felt like a loner in life, up to this point; when I met another loner. She could have been my twin sister, we had so many shared experiences, I never met such a wise individuum in all my life before.
if i am getting this right, then you are practically saying you are a demisexual- someone who doesn't experience sexual attraction until the love hormones start singing. nothing to do with functions - i've noticed you guys come in all typologies & even those of dominant Si/Se and Ni/Ne inferior - but you are sitll a member of a unique breed my man, a very rare and unique breed.
That's not fully true. I experience the same sexual attraction to woman like probably everybody else. Like the Todd from Scrubs would say: "When I saw that legs, I felt it move."
I am a person with a high need for integrity. When I was young I thought it was because I am from a military family but thats not true. Nowadays I have a different interpretation. For me the most beautiful thing to have in the World is being understood by others. Thats tho too the thing I never had in my life, cause when I was younger, I was far worser at voicing myself and my language was one of images and irrationality. I have a fundamental good ability to feel my way thru a situation. This isnt because I am so good with people. Regarding knowing what people think or feel I suck. But I have a talent for creating drama, leaving an impression or attracting the audiences attention. I can feel what they want and this ability has brought me far so far in life.
On the other hand it is the bane of my existence. Cause I am a pro when I am alone, but when I am in company people ruin it for me and the coolness I build up for myself to not be forced to show my emotions, runs down the sewer. So I have retreated into my shell a lot and in group situations I tended to be very quiet and only responded when I needed to. That has brought me into developing a reality of my own, one I like more than the real World.
Since my birth I was obsessed with the thought of 'dieing for a good cause'. This is some kind of heroic victim personality. I had about a billion of dreams when I was young, how I was to save my school, friends, the World and never asked for a thank you. Batman was my idol cause he was that dark superhero I could identify with. Cause despite all these thoughts nobody knew about it and nobody knew me.
In my early teens this developed into a developed longing for a different World and a celebration of loneliness. I was Gothic back then, walked around with dark leather trenchcoats and instilled fear in people. This was the more cool version of an emo.

When I got older tho and got back to looking normal, this isolation against the World somehow transformed into frustration about the World. I started to become hypercritical, misanthropic and self-loathing. And all the story ended in a serious alcoholic illness. To recuperate at some point wasnt possible no more, cause I was drunk every night.
And then I met my girlfriend. I being a choosey, world-loathing misanthropic who didnt let anybody near him, met his twin sister. She was like me, even worse she already tried to kill herself while I was still thinking about it.
So it wasnt like my sudden choice to change myself, no it was like meeting an angel; someone who has exactly the same problems like you do and together you can try and pull yourself together. And we managed.
The memory that remains from this shared experience is an eternal one. Its a lifetime bond that wont seperate us never again. Thats how it feels. We have had a lot of ups and downs argued, tried to find ourselves, but we are at this point and now we are starting to experience the real world for the first time on our own. At the beginning we werent able to cope with all the pressure and demand for responsibility the real world has, but we get better any day. And when we managed that challenge, we'll grow again, form a family together test ourselves as parents and learn.
the whole life is constant growth and a learning experience and my goal in life is becoming old and wise and I like to do that with a partner with whom later I can talk about everything we experienced together. Remember actions you could never remember with a stranger.
