If you care about your partner, you care about her particular needs and turn-ons - just as she should care about yours. I'm just pointing out what sex researchers say about some of the elements of typical female sexuality that have often been glossed over in a world that assumes that women are mostly asexual. If you want to ignore those in favor of being indignant, be my guest.
And yes, to some extent there is a different expectation, because as it was noted in The Atlantic article, "In general, men can manage wanting what they already have, while women struggle with it." If you don't care about that, because you don't really care about your partner's pleasure, then you will no doubt reap the repercussions of that.
