There is nothing wrong with bonding with your lizard
Maybe you can even long term teach him a few tricks that can make your both rutine easier. Positive reward its the key along side the fact that their habits animals. I would also sugest you made a smaller division in its cage wich would be the place were he sleept at nigth and eat, and wich would be equiped with a door that you could shut from outside. This would be really usefull to clean the cage (wille he feeds, Im shure if there is food envolved he will come) and during nigth you could only heat the dormitory and not the woule cage.
