to me, an unpierced cock is like a woman without heels or lipstick... a bed without linens.... a shower without soap....
A bar thru the head, vertically, horizontally... a ring thru the head or PA... or even more extreme appliances... just add to the effect of a well formed dick.
As to pain...
wanting a woman hurts a lot more than any piercing... but what kind of man would want to live without that pain? That sweet agony of desire?
Anyone who can take a tattoo can take a lance thru their cock.
And the psychological effect is wonderful... No shyness about your dick size when you can sport a 2 gauge or 00 gauge ring.... or wear a
Prince's Wand held in place by a trans glans stud...
Take that steel crap our of your ears or nose and eyebrow... and put it somewhere it will do some good.
