Is there any reason not to use VED and traction at the same time. Obviously not at the very same moment. Like say I'm following the normal starter's routine for traction (2 hours in the morning), can I do VED in the evening? Or would this push my penis too hard? Can I substitute some time of one for the other, like x amount of time VED and x fewer hours traction?
As long as you start gradually and not use the VED to the point of discomfort I think it is fine. I used both for years. Since a traction device usually compresses blood out of the glans I used the VED right before and right after traction to make sure the tissue was not deprived oxygen before and after the traction process.
