I don't know about this; it isn't completely unheard of for female managers to proposition male subordinates, it just doesn't happen as often obviously. I think it's wrong and abusive, no matter which sex does it (and to whom; (gay) men propositioning other men happens too), but I have a hard time seeing how this is "sexist" or only harmful to women, though obviously, due to inertia I think (more men being in positions of power), it negatively affects women more. I will grant you, however, that it can be argued that it contributes to keeping the gender-unequal status quo.
