I don’t know why this happens, but the more sets with an extender I do in a day, the worse circulation I get. For my first set, I’ve done as much as 1:40 with no circulation issues. I can then get fully hard to completely restore blood flow, and wait a few hours, but with my next set I’ll be numb at between :30-1:00. I can see how previous sets would affect pain or other issues, but why is circulation affected?
