I hardly would consider yourself addicted to sex. You might change that to curious and creative about adult pleasures as you grow up.....?
If you enjoy the feeling and pleasure you give yourself then continue with what feels good. Because you are learning about your body and what feels good and how to achieve that feeling you will be so much better suited when the time comes to move to the next level. Further, you will be in a better position to explain to your lucky partner just what you need. Never let someone pressure you to go further until your ready, nor let anyone tell you what the proper amount should be we all vary in sex drive. Enjoy, your growing up.
