Hi sumu, welcome to Psych Central. It's important that you understand that the age you are talking about is when boys change dramatically and can go through some gaulky stages while their bodies change a lot from the horomones that are taking over that bring about manhood. Also, your brain is still developing as well, won't totally mature until you are around age 25. Horomones can change how a young male feels until their horomones begin to level off. Yes, you are changing but this doesn't mean you are failing at life etc.
