Discoloration because of clamping

Hello guys .
I have been clamping and I got some discoloration which doesn’t bother me at all .
But this week I was with a girl and she was only sucking me and she can clearly see that my “white” dick is not so white ..
And she was like oh dude you have STD .
And I tried to explain her that this is not an STD but it was because I was sleeping with another girl with a really tight condom so my dick changed colour for some weeks .
It didn’t go well , at the end we didn’t have sex .

My question is How can I remove the discoloration .
I am white and where I put the sock and the clamp my “member” stays the same colour but upwarts towards the head oh men it is like 10-15 shades darker than my normal skin colour . This doesn’t bother me but I still want my colour to be the same .
Any ideas how to remove the discoloration .
Right now I stopped clamping and will continue with just stretches and jelqs .

Stop clamping for around 6-9 months. If you clamp again it will return.

Next time tell her the truth. You so squeezes on your penis to keep it healthy and full.

OK . Is it okey if I do just stretches and jelqs ?

Is it okey If I try hanging ?

Every exercise will change the color of your penis, I have done mostly extending, and the color has changed quite a bit.
