I am reading the rational male - Plate Theory and I am asking myself is a plate required?

My concerns is this: I don't want to cheat. I made the mental shift to be able to end the relationship.

As for now I do some reading and am not actively seeking for a plate or something, but I see my options grow every time I go to the gym. On the other hand - its week 3 and I am on level 1 in the dread game

Is having a plate the same as having orbiters for women or is a plate more?
