Although rather ambiguously phrased, I think you're asking whether I would turn the right cheek if someone slapped the left cheek - right?
Fortunately, I'm not one who puts himself in the position of needing to be slapped very often, in fact never in over a quarter of a century.
Running through a bunch of scenarios, I think if someone felt the need to give me a slap, I probably deserved it and therefore, slapping back would make things uneven again and give the other person cause to slap me a second time.
Would like to be slapped twice? No chance.
