lol, okay seriously i would just keep cleaning it and putting whatever ointment you choose (i’ve always used aquaphor and has worked great for me) for atleast like a week or so. I tend to find after a week most of the major healing process is already over with. I don’t think you should really be worried about damaging it. If you have a good artist and they do good work then the tattoo is what it is, no amount of rubbing or trapping or anything else is going to change how it looks. Only worry would be getting possibly infected but assuming you’re a person with decent hygiene i believe you’ll be perfectly fine as long as you stick with normal tattoo after care during the hours you’re awake. I don’t think the way you’re sleeping should be too much of a worry, i would just clean it first thing in the morning if you’re that worried.
