Even in an anarchist society you will have "powerdynamics" like a partner that is more conventionally beautiful, has a more prestigous job like say surgeon or is simply very popular with a lot of people. Sure I agree that we should strife to reduce the imbalances and even the playing field but under the current oder only so much is possible. Which is why I wouldnt mind an increase in the Age of Consent since it would be a pragmatic thing that could actually happen (at least on paper).

And yes I think a Boss / secretary realtionship is problematic but it should be allowed under the current system. (Assuming consenting adults). Of course we should try to eliminate the need for bosses but that is not something that is going to happen anytime soon.
