cold & blue
From a physiological & PE point of view what are the disadvantages of this occuring whilst hanging? My dick becomes quite cold (obviously this can be overcome by applying heat) and blue whilst hanging, should I;
stop, massage and allow circulation and rest before commencing a new set?
Does coldness and blueness have any long-term effects on the circulation of blood within the penis.
P.S between each set I massage quite a bit to restore circulation.
