Tingling and numbness means that somehow you're putting too much pressure on your nerves. It might be the ropes/ties, or it might be the position. So try process of elimination. Try a position that doesn't stress the joints, like spread-eagle. If you still get tingling, it's probably the ties. If you don't, it might be the other positions.
A good basic rule is that after the ropes are on, the dom should be able to slip two fingers between rope and skin. If he can't, the rope is too tight.
