Hello I am 25 years old and have a problem with how i look and the way it makes me feel. For some reason or another, i havent fully gone through puberty, at least i think. I thought that maybe i just havent gone through it yet but now that im 25 its starting to affect me both physicaly and mentaly. The obvoius symptoms are very little facial hair, body hair, small testicles. I have eard about people with low testosterone levels and how that can affect your mood and concentration wich i have problems with. Im kind of depressed about it because my sexual drive is minimal. Even though i get erections when i am in the act it goes away quickly. Is there any advice you can possibly give? Im in the dark with this one and im not sure where to start. Thanks for your time.
