Black magic? White magic? What would you teach? What is your competence,experience,knowledge, for you to teach?
You say that you are a "Wicken" (sic). But you are not old enough to be initiated. So you may have read about Wicca.But when you refer to black or white magic, that shows you don't really know enough to teach.
Study more. Read more. Learn what magic actually is.
Blessings to you from a very old witch.
