Nope - most guys find it gets more pleasure-sensitive as it swells up.
Does your head swell much?
Are you sustaining the pressure for long periods? That tends to cut off the supply of fresh blood, which might lead to numbness.
Better to vary the pressure (pulsation pumping).
thanks for the reply. Yes my cock head does swell. I keep pressure for 15 minutes max, but I will try to vary the pressure more and see how that goes. thank you
