I read the 4 or 5 first answers to this thread and then started to write an answer earlier today, but coming back now I see the thread has grown really big already!
I'm still posting what I've written earlier, and will read the other answers later on, to see what is other people's take on the issue. I'm sorry if what I've written is redundant. Maybe I'm way off. These are just my thoughts on the topic right now. I'd already tried to reflect on this issue, without coming to a definite answer.
I had no idea who this Ariana Grande was, so I read the article Joe linked to, and then checked some of her lyrics and music videos, which are quite telling. From what I gather, she's apparently a kind of toned-down version of Miley Cyrus. A perfect illustration of what's wrong about this world, in terms of 'expression of sexuality', the objectification of women (or I should rather say, women, men and children), the distorsion of men/women relationships, the corruption of sexuality under the guise of sexual emancipation, the need for showbizz industry to force women to expose their bodies because it sells (and manipulating them into believing they do it "by their own free will", as an "artistic expression of sexuality" )
Just to make things clear, I don't think it's right, and I'd never justify such behaviour towards women: insulting her/assaulting her/thinking she gave you the right to treat her like a sexual object/a thing to use and abuse simply because she sings 'sexually explicit' lyrics, dresses provocatively, or was drunk at a party, or simply looked at you. Or just simply because she's a woman, and it's "the way things are" ("Boys will be boys", and it's normal to be 'aroused' by women). So, however a woman dresses, whatever her behaviour, however she looks or talks, this kind of behavior / abuse is never OK.
However, given the world we live in, I think it's disingenuous, or very naive on Ariana's part to not expect that kind of sexist behaviour/comments from men, because most of them are just very sexually and emotionally immature, and are taught from a young age to objectify women!
Women are required to be sexually desirable in the showbiz industry (and in general) if they want to succeed. The more provocative the better. So she just perpetuates that state of affairs by complying to stereotypes.
I don't see such "art" (the 'sexy' music videos, the explicit lyrics) as an expression of "feminine sexuality". But in her ignorance, because of the general programming, Ariana must think she's a free, emancipated woman.
And men, most of whom are immature emotionally, just react to this kind of display of feminine bodies and 'invitations to sexuality" the only way they know how. It's mechanical, programmed behaviour, natural in this world. I don't see how we can expect them (esp. young men, most of whom learn about sexuality by watching porn) to behave in any other way, really.
From the perspective of the Work, I'd say a more spiritually developed man would see this kind of so-called 'free expression of female sexuality' as trivial and infantile.
I'd say the first task, if we want to get out of this mess, would be for men to grow up emotionally/sexually, and then the rest would follow naturally. Not the other way around, i.e. women having to cover themselves in order to not 'provoke' and 'arouse' men.
An emotionally grown-up man would not be aroused by such display. A woman trying to incite a response from him by being 'provocative'/sexually suggestive would see it doesn't work. She'd stop doing it to please him (why else would a woman dress provocatively? Just for the heck of it? I don't think so). She'd stop manipulating. She'd be freer to be herself, freed from the pressure put on women by society to look good/sexy in order to 'get the guy'.
The emotionally/'spiritually' developped man would explain to the woman that she doesn't need to resort to that kind of behavior to get his attention.
The woman could try to impress/seduce him, but it'd be the man's job not to react to it (master himself), 'saying no', while treating her with respect. Seeing her, and treating her like a human being first and foremost. A human being who might be wounded, and just needs to grow up, and learn what is healthy and what is not.
Ideally, men and women would work together to overcome their programming. But as I said, first, I think it'd be the man's task to overcome his urges so the woman can be "free" - free to be, and to become whoever she wants to be. Don't know if that makes sense.
Relationships would then become more authentic, spiritual and true.
Sexual 'needs' would only be the need for partners to bond emotionally/spiritually. Not the other way around (I have sexual needs => I need a partner).
I can only speak from a female point of view, but I guess for men (who are supposedly more 'sexually driven) it'd become easier to master those urges as they grow older.
For the education of young men, i.e. learning how to properly treat women and channel their sexual impulses / hormones positively, in a non-harmful way, in THIS particularly screwed-up world devoid of any good, male role model (there're only so many Putin's out there), I don't know what could be done, realistically.
Really, we just need good male role models, and the rest would follow and come into place. Those are my thoughts anyway.
As an aside, I'd like to share that very funny video of a young woman's hilarious (and very smart) response to sexual harassment in the street. I think it sums up perfectly the emotional/sexual immaturity of a lot of men these days: they make stupid, sexist comments not particularly because they're horrible jerks (ok, some may be), but because they're just big babies who don't think at all. As soon as the object of their sexist comments replies to them and starts to actually interact with them - as soon as they realize that what they have in front of them is a feeling/thinking HUMAN BEING (not a sex doll / an object of fantasy), they have a kind of meltdown and become stuttering idiots. Even if it's funny, it's actually quite pathetic and sad and speaks to the lack of maturity of a lot of men:

Last (this is getting long already), I think those comments from the C's provide clues as to which direction humans (both men and women, but men first, by learning how to overcome/channel his urges creatively) should go if they want to sort out this mess:

Q: (L) Now, I was just reading in "Bringers of the Dawn" about male energy and female energy and it says: "We have said that the male vibration will transform in a very short period of time. We will not tell you why or how because some of you will consider it to be entirely too ominous, however, we will say that as the waves continue to come there will be a unilateral rising of consciousness within the population. At a certain point, when men are in the deepest point of mastering feeling, the feeling center will be activated. This will either occur gently or it will be blown wide open." What will be "entirely too ominous?"
A: Energy redirection.
Q: (L) Energy direction is going to happen and that is what you are saying is the ominous thing here?
A: Overview.
Q: (L) Well, what does energy direction specifically mean? What kind of energy?
A: Sexual.
Q: (L) And this is going to be the ominous event that would frighten people?
A: Repercussions.
Q: (L) What are the repercussions?
A: Many.
Q: (L) Could you tell us some of them?
A: First you must figure out answer to number one.
Q: (L) Well, sexual energy "redirected"; does this mean women will stop having sex with men?
A: Not exactly.
Q: (L) Am I close?
A: Yes. Men will lose most of their drive in favor of more spiritual pursuits. It is the sex drive that is at the root of most of the historical aggression and lack of feeling on the part of the male.
Q: (L) Can we tell others?
A: Might cause turmoil but up to you.
Q: (L) I noticed that at about the same time I began meditating heavily that my drive plummeted. Is this because of the meditation?
A: Yes. Females will lose some drive too. But how will humans react to this, that is the question. Will they be prepared?
Q: (L) Does this mean that everybody is going to lose interest in sex?
A: Will have much less and must learn to relate to each other more spiritually.
Q: (L) Is this because one of the major drives of the human being is for contact and, up to now, this has been manifested through sexual union and without the sexual urge they will be forced to find other ways to relate?
A: One would hope so. You are all moving toward 4th level which is less physical thus you must learn this existence in order to pass through into the 4th level.
Q: (L) And those who do not learn will not pass, is that correct?
A: Yes. Some will be relieved. It depends upon how advanced one is.
Q: (L) I have drawn a sort of conclusion about some of the activities of the Lizzies and their abductions through the Grays and so forth, and it seems to me that these excessive numbers of exams, gynecological, reproductive or whatever exams might possibly be a screen for a process that is used to extract life force or energy from the human being, through the basal chakra, the sexual chakra, as I understand where the life force enters in. Is this idea correct or on track?
A: Close.
Q: (L) It does seem that the Grays and Lizzies are abnormally interested in sexual activities of human beings, is that correct?
A: Yes.
Q: (L) Why are they so inordinately interested in this and why do they practice sex, sexual aberrations, or do they have a tremendous sex drive even though they are fourth density beings?
A: Too many questions; one at a time.
Q: (L) Do they have tremendous sex drives even though they are in fourth density?
A: No.
Q: (L) Are they interested in sexual energy simply because it is life force?
A: Partly and also desperately to stave off change in order to retain control.
Q: (L) What changes are they desperate to stave off?
A: To 4th level.
Q: (L) They are trying to stave off the 4th level change. Can they do that?
A: No. Also hoping to retain control even if change occurs.
