any cane hurts less. It is all in how you use the cane, not in the material used. Now granted, a carbon fiber cane will hurt more than a rattan cane when used with more force. But you can make them both hurt very little.
Pain and the tolerance for pain grows as you experience it. There is a thread around here that talks about it. Basically think about how a runner must train to go the distance. They can't start out running the marathon, first you must run 100 yards, then increase it. Build up your ability to endure the physical requirements. So it goes with pain during BDSM. The more you do it, the more you will be able to take. When you have gotten yourself able to take some good pain, stop for a while, like a month or so, then try to go back to where you were before. It ain't happening.
