Boyfriend got new tattoos

My boyfriend of almost a year just went and got 3 new tattoos, 2 of them making a sleeve. Last I saw him a few days ago he only had 2 small ones and seeing him now he will look very different. I like tattoos but don’t have any. But I’ve known him without them for so long, it’s strange to me seeing him with ink up and down his arms literally almost overnight. Is it wrong of me to feel like I’m going to see him differently now? I love him and would never leave him for something like this but for some reason a part of me is really sad that he has changed this part of him so quickly. I feel like when i see him I’m not going to feel like I know him. Help with a new perspective please?
