Why hasn't my penis grown at 19?

Your description sounds like penile deviation may be present. If trauma occurs nearer to the groin that can change how your penis sits. When you mentioned the bullet kick back episode with injury on the right hand side, it could have caused things not aligning down there anymore. Because everything down there is still in the process of healing, your penis might have moved into a different position by itself. If there’s no pain occurring at this time, that’s good news. Wait for a while longer and observe if things get back on track naturally. In case they don’t or start feeling worse or any other symptoms develop, then it’s best to have them looked at closely by medical personnel.
