I'm liking this piece by Hugo Schwyzer right here.
Its a post on why it may be a bit presumptive to go straight to "he wants to degrade and humiliate her" as to the reason men want to give women facials (facial: ejaculating on your partner's face). A bit of background on the origins of the facial.
Glickman suggests that the AIDS crisis and the concern with safer sex was what made the facial popular. "Cum on me, not in me" was a popular sex educator slogan as far back as the late 1980s. Ejaculating on a woman's stomach, however, usually meant that the camera wouldn't let the audience see the actress' expression. But if the male actor came on her face, the viewer could see two things at once: evidence of male pleasure (symbolized by the ejaculation) and the equally important sign that a woman's reaction to that pleasure mattered. With sex now so dangerous — and HIV particularly likely to be spread through semen — facials were relatively "safe." But in the era of AIDS, they were also compelling visual evidence that a woman wasn't threatened by a man's semen. In that sense facials were, almost from the start, more about women's acceptance of men's bodies than about women's degradation.
I think this is a plausible explanation that could serve as an almost polar opposite of the "humiliation/degradation" view on facials.
I've talked about how many view male sexuality as dirty before. I wonder if the "humiliation/degradation" crowd are starting from the destructive premise that since male sexuality is dirty then giving a woman a facial is a way to "make her dirty". Just like with other sex acts the facial may be seen by such people as another way that a "pure woman" is made "dirty" by having sexual contact with men. Which may be why some people have a hard time with the idea that a woman may not care if a guy gives a facial and a really hard time with the idea that she may actually like it (there's a small anecdote in the article about a woman who experienced her first orgasm after getting a facial). But let's go a bit deeper.
It probably won't take much effort to realize that a lot of males think that their sexuality is dirty. They are sex hungry brutes that need to have sex with as many women as possible as fast as possible (its a sign that they're "real men" right?). So what if a male thought that the sight of a woman letting him ejaculate on her face and not freaking out about how "disgusting he is" was a form of acceptance? A sign that she wasn't repulsed by a part of him. Proof that she is okay with coming in contact with semen. Because let's face it (see what I did there) if a woman is letting you cum on her face then that probably means she trusts you if for no other reason than a lot of bad stuff can be transmitted through semen to skin contact.
And yes I said "letting him". This is contingent on consent. There is nothing wrong with a woman that doesn't want a guy to ejaculate on her face. She could have any number of reasons from having a traumatic experience, to she's allergic to it, to even the idea that she thinks its disgusting (and yes its entirely possible for her think semen is disgusting while not thinking the guy its coming from is disgusting) for not wanting it done but those are neither here nor there. Also more than likely a guy that's looking for affirmation, validation, and TRUST will be respectful enough to take a woman at her word when she says she doesn't want a facial.
That bit about trust will eliminate from this line of thought any guys that actually get off on doing it to her for their own pleasure whether she wants to or not and in their sick minds her not wanting it is a usually a bonus. They are in it for the lack of consent (notice that they don't even ask or do it anyway after she says no), humiliation (because there aren't many things that will generate humiliation more than having something done to you against your will), degradation (thinking that them doing it to you anyway is a sign that you are beneath them) and who knows what else. So bear this in mind.
In any case, humiliation and affirmation aren't incompatible reactions to the same act; a feeling of indignity when your partner ejaculates on your face isn't contingent on his intending to demean you.
In short the fact that you find facials to be disgusting doesn't automatically translate into "he wants to do it to humiliate me".
Personally I think that this could hold true for guys that want to ejaculate on a woman's face but don't want to do it to humiliate her, who are probably operating from the thought that if she is being humiliated (and I don't mean "she gets off on being treated that way but its consensual" I mean "she just had her boundaries violated in a serious way") then she's not going to want to be with him. What person wants to be with some that doesn't respect them?
Two things I want to add:
1. I'm not trying to pass this off as proof that no guy has ever wanted to give a woman a facial for sole purpose of humiliating her. Yes there are jerks out there like that.
2. Despite this being written in terms of man ejaculating on woman this could probably be applied to any (and I can't believe I'm about to say this) ejaculator/ejaculatee relationship. In fact I think the existence of facials in male/male porn challenges the assumptions that facials are about humiliating women, as the article notes. (unless you're one of those folks that traces everyone back to a hatred of women).
