havent hit puberty at 16 (male). i have a small amount of pubic hair around the base of my penis which i have had for around 3 years and a little under my arms. other than that nothing else has changed my penis and testicles haven't grown at all my voice is still really high and i am only 5"2. recently i have been feeling depressed about the situation and it is causing me to stay home more often because it is embarrassing to go out as people think i'm about 12.
you most definitely need to see a specialist. a pediatric endocrinologist. this needs to be done asap. you will need to have a series of tests to determine the reason(s) for your delayed maturation.
