Pain isn't always a part of a sub's existence, but in most BDSM relationships, it does play some role. When your Dom is someone who wants to see just how much pain you can take, you need to be ready to take it all - and to do so with grace and appreciation. After all, it takes a lot of energy for your Dom to give you the pain that you will receive from them. You can become a painslut, someone who is eager to accept pain and who is always ready for more, no matter how large the welts and bruises might become.
