38 year old Asexual here. I was never traumatized or abused, I simply have no interest in sex. I have no desire for it.
Now I am emotionally challanged, I'm not sociopathic or psychopathic, I still have emotions and care, I simply don't know how to make and keep connections with people. I have very few friends and don't keep in contact with the ones I do have.
If I was programed then the Designer of the Infinite left out part of the code.
