I don't think a facial is mysoginistic. Any sexual act is fine, as long as both the guy and girl agree to it.
I think if we're being honest, facials do have an element of mysoginy. Or if not mysoginy, then an element of dominance. Most women (and I'm speaking as a general fan, and a past practicioner of facials) don't like them, and it's not difficult to figure out why. Personally, I enjoy seeing a facial in porno, and having thought about this at some length over the years, I think it's because at the very least, it's evidence of a woman's compliance in being dominated, or controlled, or - and it has to be said - possibly even humiliated in some way.
Now that, in and of itself, may have an element of mysoginy, but I do think it's harmless as long as both parties consent. I certainly don't view myself as a mysoginist or sexist or any other -ist, but the fact millions of guys like to see facials perhaps means it's just symbolism of some innate, can't-help-it, male desire to dominate, compete and control.
Anyway, with the right girl at the right time and in the right place, it can be damn fucking sexy.
