Docs can you explain, is my need to masturbate a weakness?

No: Common sense here. It's the natural way to learn about your changing body in preparation for adult life, and it keeps the pressure off so you can do other things. All male and most female teens enjoy themselves in this way, and anyone who tells you it will damage you physically or spiritually, or you should despise yourself for it, is simply playing a cruel game with you. Think for yourself.
