Not particularly more-so than most male character depictions. It just looks like a martial arts pose/posture with an artstyle with heavy musculature. The pose does not really look like a sexualisation of Ryu, overt or tacit.
I mean, at the very base of this premise of the comparison (and really the thread as a whole), is that [many, most, all] women and gay men are particularly attracted to heavy musculature and a heaving chest. Some may be, I suppose. And that the type of ridiculous sexualised poses that female characters are often depicted in would even appeal to women en masse. It may appeal to some, I suppose. But I don't think the point of Hawkeye-ing female depictions is to say "This is attractive to me. I want objectification of males like this." rather it's to highlight the ridiculousness of the female objectification in media.
Well maybe I'm reaching here but it struck me when I looked at it that it seemed to bear a resemblance to that type of pose I posted. It's certainly not as brazen as anything we see for female characters though, I agree. And, though it's true that the same type of things are not attractive to both men and women, when it comes to depictions of the human body many techniques could likely apply across both genders to achieve a desired effect.
