Dealing with Physical Changes?

Hi guys. I'm wondering if you've noticed any physical changes to your body during rebooting?

I have 3 areas of concern, but they're a little bit weird:
-The skin on my "male anatomy". I noticed before when I would M frequently it was darker than the rest of my body. Now that I've stopped it's becoming lighter, but there is a dark ring going all the way around, and the skin is more wrinkled there. Like a deathgrip mark. Is this weird? I'm worried future partners might think it's unappealing.

-During the day I don't really feel the urge to M at all. Unfortunately, the past few nights when I go to bed I feel this kindof "pee urge", like that one area of my body really wants to have an O. I don't really know what I should do to make it go away?

-My testicles have been hanging kindof low the past few days. I was reading some tips on how to exercise them, but I couldn't decide if this is a valid idea or kooky. One exercise was to gently pull them down, the other was to push them up towards the belly. Any suggestions on this subject?
