First off, what type of KS are they?
Best time to introduce them is during brumation (cooling period) and they will bond without all the initial nervousness. But if the nervousness doesn't bother you then you can place them together at anytime (as long as they are wll fed)and just wait for them to get used to each other. Removing one all the time and reintroducing them will not solve the problem until they have suffiecint time together..
I recomend keeping sexed pairs together if you feed them well.
If you introduce a pair during non-brumation months it is expected that one or the other of the two will be nervous. This includes cruising around trying to get out of the cage,nose rubbing, striking ect. But after about 48 hours they will calm down. One is just nervous because they feel they may be a potential food item. But once they bond they will be alright.
On another note about cannibalism in kingsnakes. That usually happens when one or both are not being fed enough. So make sure you understand HOW MUCH is enough. Most people DON"T feed them enough and even on this forum you will get varied opinions on this. Give them as much as they will eat.... Always give your snakes choices in food, temp gradients and humidity. They know what to do.
These snakes are found together in nature. On top of that there would be no kings if they were natural cannablists.
