Welcome Kira, it is nice you have found this place and joined us.
From your short introduction I will assume that in Real Life, you truly are physically with your Master.

We all have different needs and experiences. We all, as well have different kinks and pain tolerance levels. I find it curious that you endured nipple clamps for (what it seems from your description) over 24 hours. What kind of clamps are those?

Dear Kira, please take this for what it is - a well intended advice: no matter what position in Ds relationship one holds, knowledge can only enhance your experience. Read, read and learn (and not only fantasy - read up on safety, how-to etc.) about the BDSM, about the techniques and what are recommended and tried things and guidelines for “play”. One can live this and live it to the fullest making it the most fulfilling life journey, or one can go into it blindly and hope all works out well. I personally would recommend the first, safe and sane path - some things are better left to fantasy.

May you enjoy all your Master wishes you to endure!
