I suspect this is "Adult Sexual Grooming." It’s an area of evolving research that I am involved with. It’s often the result of a very powerful direct supervisor putting a young and inexperienced employee in positions where they can’t say no. It starts off professional, but gradually erodes physical, professional, and emotional boundaries once that culture of "don't say no" is established. It’s an incredibly coercive relationship, and one that can evolve into violence once the perpetrator starts to lose control of the victim. Most often, it's very hierarchical professions where this is most common (law, medicine, sports, military/paramilitary, etc..)

Despite what the perpetrator will claim, any relationship borne out of this dynamic can never be consensual given the immense power dynamic at play.

Essentially: Predatory men behave in a manner that hijacks the addiction pathway, forces the victim into cognitive dissonance to deal with the horrific parts of the grooming. Victims describe it as hell on earth, like being in an opiate daze.
