Interresting philosophy bigmuscles_averagecock, i believe it makes sense.
I have longer frenulum, so retracting my foreskin doesnt cause the piss-slit to stretch and make better aim to the jet. When i sometimes dont retract mine, the foreskin redirects it in 2-5 different directions, and its really like a need to retract to prevent this. And with retracting, the jet is nice, thick and forceful.
SirConcis, i think we have very similar situations (at least before your partial circumcision). Sad you let them cut yours, but good that you were clever enough to leave some of it - congrats on it!
I have almost 0.5'' of overhang, and myself have learned to retract while pissing cuz otherwise some piss would be left there, even after shaking and retracting after the pissing, and it would smell later. Yeah, its other thing after night-jerking and not cleaning it, there is smell, but not that awful.
After retracting i hardly ever have piss-stains on my underwear.
