Is traction good or bad for blood flow?

[Bendingoverbackwards]

Hey all,

Just wondering if traction is good or bad overall for blood flow to the penis? I was thinking if my member was injured and had a priapism of sorts it might not be good to get a suction traction device like the phallosan because wouldn't it just keep all the blood in there? Which should sort of be the exact opposite of what you want to do? Any advice would be appreciated.
