real2123, When pumping, start slow. Do the first session without the mod. Taking a week apart deconditions your penis; therefore spots occur.
So, next time you pump, don't use the mod. Go slow, go long. The second day, you can try use the modification, but patience is advised. I know you said you start slow again, but start even slower.
