Aftercare instructions for large tattoos?

Simran • 18

I just got a fairly large thigh tattoo. It looks like this:

I just got it two days ago. I have been washing it with a mild antibacterial soap 2x a day, letting it air dry, only showering for 5 min a day, I sleep with the tattoo UNCOVERED after applying a thin layer of coconut oil, and applying a thin layer of coconut oil to it 3x a day. I haven’t recovered it since the initial covering when I first got my tattoo. Is what I’m doing good or is this a recipe for disaster? The internet is telling me so many different things and I’m just so confused.
