Is it wrong to be attracted to my god-brother?

Me and my godbrother have known each other since we were 3 (him) and 4 (me) years old. Our moms were really good friends and thus decided to have a godfamily, so his mom was my godmother, his sibling was my godsibling, and vice versa. We lived across the street from each other until they had to move when we were in middle school. Sometimes we celebrated our birthdays together since they were only less than a week apart. Growing up, he was kinda attracted to me but of course we never did anything, as that’s my godsibling lol. I haven’t seen him since we were pre-teens and I just reconnected with him on Instagram. He’s lost his mom since and I’ve lost my dad.

I’m not gonna lie, I’m very attracted now. He’s grown his hair out and he’s just...cute. And he has muscles. He no longer has that little boy look I remember. He just got out of a relationship so he’s single now too. Not sure if he’d be ready to jump into another one but I am attracted. Is this wrong? Lol
