Puberty/Testosterone problem

Patient

Q: Im 19 years old. Im 6'3 but only weigh 140lbs so im very skinny. I also have no facial hair and people mistake me for a 16 year old rather than 19. Is this a result of my genetics or could it be low testosterone?

Symptoms:  No facial hair
no weight gain
trouble building muscle
child body
girl trouble
