Nothing is more impressive and representative of power than a thick, veiny cock. A few observations. Those who are uncut have more real estate to display veins and that uncut area is thinner skin and more vascular (what a shame to throw it away!) Adding oil (an old bodybulder's trick) and being blessed with thin skin also helps. Constriction maxxes out the potential. Mule has the prototype for the perfect veiny cock although there are other very impressive entries here. Great thread!
