(They or he pronouns)

I recently called things off with a KH, not because they did anything wrong I just wasnt feeling it. I always ask for more than I can handle. So I’m trying to do kink by myself but I want to keep it interesting and add some structure.

I saw a post somewhere were someone said each time they do chastity they extend it by trying to beat their old time. I only lasted 17 days about before I snapped. Part of it, I think, is that I wasnt edging enough. I also think for whatever reason the dynamic that I encouraged my KH to take with me was causing a bout of depression.

Does anyone have any advice on how to do self chastity and edging without cumming in a way that is fun and structured and also challenging in a good way? I want to keep doing kink but I always go overboard if I have a dom/kh.
