Discoloration from air pumping or MT2?

I started pumping at the same time I began using MT2 for tanning. At first, I thought the dark discoloration was from the MT2, but now I'm beginning to wonder if it could've been caused from pumping. I pump for 10 minutes, rest for 5, then pump again for 10 minutes at the suggestion of my Priapus shot doctor. WTH is causing the darker discoloration? What say you?

I say that it might be from the pumping. It does not matter how much you pump if you don't tell us how familiar you are to pumping. If you are unconditioned and have never pumped before (or maybe pump too intense)- discoloration will almost always be present. If it bothers you THAT much- just give yourself a break, wait for it to go away and start slowly
