Really, folks, thanks for your replies
I don't think that I have a problem with looks.
I am a person who likes discussion, talking about interesting things in the world - on a scientific basis - and not about which actor married which singer or other things, though I respect anyone who prefers choosing that kind of information.
I like to talk about astrophysics, comets, evolution, neurones, brain implants, technology, nature etc. and - as far as I have personally experienced, there are nearly no girls at all who are willing to engage in a conversation dealing with such topics.
Typically a girl of my age will talk with me in a flattering, seducing way in the first maximum 2 days she knows me and scroll on to her next target.
I also go to clubs, etc. with friends, but always bring a book or a scientific journal with myself or I'll die out of boredom. Sometimes I even write poetry while my friends are on the dancefloor (I like to play concentration games with all the loud music).
When I said "back to the books, nerdy" I meant what happens almost always in the club or at parties when a nice girl approaches me. We start introducing ourselves, she does some showing off, talks about this and that and clearly shows that she does it without much passion, fluffs two or three st*pid jokes that I have heard for the N-th time in my life, sometimes pushes a bit forward (but I'm not a fan of one-night-stands), but in most cases leaves for the next friend or the next table, and I go back to reading the books (which are often more interesting than that kind of "experienced" girls, HONESTLY!).
Probably, out of "experience", they avoid "immature" guys like me because they don't immediately obtain what they want?
As I said, I'd be stimulated only by something serious. A person who knows to passionately listen to you, and does not just pay you 100 compliments just to get you into bed, and thereafter forgets everything she told you.
A person with whom I wouldn't have to act.
A woman who knows how to discuss, debate, shows no fear to be herself and has more interests than just sex, love and reputation (I said, not ONLY them).
The younger girls, in search for new experience, "immature" like me... they simply gave me the impression that they would accept me for who I am...
And they would learn from me, with passion. They would learn from me as if I was a point of reference to them. As you said, as if I was their "mentor", their idol, their role model.
I was their first experience (or among their firsts)... wouldn't I be able to make a change to the world's eternal stereotypical "hot chicks don't become scientists/hot, blonde chicks are always stupid" (which is sadly also true as I told you from my discotheque experiences)
That's what I hoped for.
Ok, 13/14 is young, I'll discard them... but there are even 15 and 16 year old girls without much "experience".
