Simply because you are afraid of them,possibly consider them as somehow superior to you.

At your age the personality is set,no use attempting any radical change for"hormonal"reasons.

From your past posts you seem the prototypical "nice guy"...and despite what you've heard there are women,equally shy and somewhat insecure{sorry,it's the truth}seeking the same.

Drop the emphasis on physicality for one,everyone wants the SAME DAMN THING! One thing's for damn sure,you ain't gonna meet 'em in bars! hang out at the library,join up{sounds corny,but works}with some local groups,volunteer at a soup kitchen,thrift store,wildlife blaaa,blaaa,blaaa,you get the idea.

You seem to have the personality that would thrive in a 1 on 1 relationship so throw any physical considerations out the window and be open to ANY nice girl,whatever her looks,which,by the way are the first things that fade......
