There is no such thing as being too young to masturbate. It’s a personal decision. Most people masturbate, and the age you decide to start is up to you.
As long as you do it in private, masturbating is harmless. It’s a good idea to set boundaries in your home or living space. Find somewhere where you can be alone and speak to your family about knocking before they enter your space. Everyone deserves to feel comfortable exploring their own body in private.
