I am relatively new to this topic. How does Denial December exactly work? What are the 'rules'? I know there are no strict written rules, but what would be allowed or not allowed during Denial December?

From what I understand, reaching the edge of climax is allowed, but ejaculation is forbidden, or anything related to climax and beyond.

Is wearing a chastity cage mandatory?

I read somewhere that on December 1st, you should edge once, on December 2nd, twice, on December 3rd, three times, and so on. In another place, I read to edge as little as possible in December.

Which one is correct?

I would greatly appreciate it if someone could explain Denial December to me in more detail.
