Welcome to the forum! 
A bazillion - noooope: quality over quantity.
However, the subject is vast, with magickal traditions in every culture worldwide - you have to learn the landscape to know what a) quality is, and b) fits you and your temperament. You can’t study what you don’t know exists. A good library is ideal.. and very satifying.
Aural traditions - they apprentice or disciple to a teacher and are taught in person.
So… you don’t know how to actually use sigils, cos jizzing on them is not it. 
Jizz can be an offering after you get contact though. 
Compare what you are doing with this and then come back with specific questions if you have any…
