Another healing question

Sorry for another healing question. I am getting a tat that will start on my back and flow down onto my ass. The question is how much trouble is it going to be to heal the part on my ass? Also do people that have tats there have trouble (after they fully heal) with the area around the waist line where pants will rub? I already know it is going to be "a pain in the ass" (you know you were thinking it). Anyone with experience with this would be great.

Just wear loose clothing for a few days and it will be just fine !!
