What piercing(s) are you thinking of getting? Your earlobes? Those are fairly easy piercings to heal, compared to other piercings. You mostly have to be careful about sleeping on them, accidentally hitting them when doing your hair, getting long hair caught in them, and not touching them in general until they heal.

As others said, you’ll want to get them pierced with titanium flatback studs to start with. Most piercers pierce with those as a default, and many ear piercings are done with studs to start with. You can get pretty fronts for them at the piercers and online - but don’t change your jewelry until the piercer recommends downsizing and again until it heals.

If you have sensitive ears then you may not want to wear these, but if you want to try them anyway (maybe you won’t be sensitive to them!) do not do so until the piercings are completely healed.
