H all,
I'm 21 and i lose my erection during masturbation. I have never ejaculated because of this and I have been to the doctors but all they say is "Viagra". I do have a disability called friedreich's ataxia which affects my stamina and spine. I am not sure if this is the cause but its affecting my confidence when taking to girls because I don't want to have sex and embarrass myself.
Also my penis is small and doesn't seem fully developed, could this be due to my spine condition?
Find a doctor who can check your hormone levels, including testosterone. I don't know much about your specific Ataxia. If your lower spine has any nerve damage, this could be a problem. If you being followed by a specialist (neurologist) good question to ask
