Just in need of advice

Hey everybody! My boyfriend is going to get a pretty big tattoo on his forearm this Friday, and I was just wondering what would be the best way to ease the pain and make the healing process go by easier. His taking days off of work to make sure he doesn’t get it dirty and lower the chances of an infection. I have been reading on here about tattoo goo and the use of coconut oil? Which one works best for a guy and is there any other things we should take into consideration?
