@dickerschwanz have you found a solution? I've posted some oils and creams which I'll use in my thread.
Damn, that's some threads you pull out from way back
but I give you a good answer for the interest.
Yeah I managed this problem to some extent,.. first step is to avoid discoloration.
It is blood(iron) pulled into the upper skin layers trapped there.
Happens with jelqs, pumps, clamping.. . Key for me is to ease into every expansion gradually. Don't pump up fast, don't clamp 100% first set, don't jelq at max. first set.
With pumping you also want to not release the vacuum all at once cause this shuts the skin layers fast, trapping the blood.
Then after any exercise that turned your dick dark, immediate light jelqing/massaging, that pushes the blood out of the skin. I never miss that step.
To get rid of existing discoloration without any means it takes a lot of time with no PE at all.
I had severe discoloration years ago after a heavy pumping routine. What I did was applying DMSO mixed with ascorbic acid applying it daily. DMSO opens the skin and ascorbic acid is an antagonist of iron(blood). To do that you need to inform yourself about dmso a lot before doing it!!!(I written about it somehwere). This can take weeks or months depending how often you do it.
One day I miscalculated the mix and had too much DMSO in it like almost pure (normal 7 parts dmso and 3 parts water with vitamin c dissolved to saturation) which basically burned my skin AND the discoloration away. Had to put healing creme on it for some days and the skin came back fresh with it. But lots of pain lol.
But overall if you do PE discoloration is a part of it..
