It is perfectly OK to only code at work, you can have a life too
Does a lawyer do law outside of billable hours? Some do pro-bono. But not the majority.Does a doctor practice medicine outside of his hours? Again, some work at free clinics, but generally no.Do veterinarians like it when you ask them to take a look at your cat when they're not in clinic? No. Almost always no.Work is work, leisure is leisure. If coding is leisure for you, that's great.
