You may find that you start doing a few porn alternative activities and that you enjoy none of them. That's not a problem. It is quite normal to start doing something and notice that it doesn't fulfill you after a few weeks or months. Even if you find a hobby that you love to death, you may still outgrow it after a few years. Priorities change, and so does your wants and needs. The key to finding something you love is to keep trying new things. Never give up learning. Never give up trying to become a better person.
