Hey sorry I had to post it here but I tried to call you and I can't get a hold of you, and you didn't respond to my text.
I found the information that you asked me about....
It's called pruritus anuses, in other words itching anal - it's quite common and is not dangerous. It can happen if you don't wipe your ass properly.
It can also be a sign of hemorrhoids in or near your anal hole, I still recommend you to go see the doctor.
If kept clean the anal odor should be bareable
Wash it and keep it real clean and wash your hands before you scratch so you don't get pink eye like last time.
I hope my answer helped you.
Take care

mate?
