Good guide for learning female anatomy?

I tried masturbating 3 years ago and got so scared because i felt a hard protruding nub so after that I quit. Now I am finally realizing that that nub is my cervix and I have never felt so dumb. I never got sex ed in school and I can't believe I dont even know my own body. Are there any good websites or anything that could give me like a crash course in female anatomy?
