The short answer is simply yes -- confidence/dominance is a larger slice of a man's social capital pie than a woman's, and so he suffers more if lacking in that department, just as women suffer (or benefit) more from physical attractiveness. Of course, negative features are still bad for either sex (what girl wants to be socially awkward? what guy wants to be ugly?), but the differences in importance are there, and largely ingrained.
Severity plays a big role, though. A shy guy might have it rougher than a shy girl, but not as bad as an extremely shy girl.
This rounds up what i was thinking, adding the word "typically" after "yes" just to not flatten the curve.
