you definately need to go to a doctor about this. what are your hormonal problems... are you already seeking medical help for them? perhaps this is what is causing it, but all i know is it is not normal or healthy for a boy of your age to never have experienced erection. please go to a doctor. and keep us posted on your progress x
i read your other posts there and i can feel your frustration but i am afraid i cannot help. i am not a medical professional; nobody here really is. i didn't understand most of the information you gave, there. i'm sorry. i can only hope that you can find a specialist who is able to help you.
