...The difference is that the developers probably aren't designing the male animations to be sexy. If they might be incidentally sexy (I would challenge you to find more than a handful of women who think that male warden/hawke/inquisitor's animations are particularly sexy), but based upon developer comments, they designed the female animations specifically to be sexy.
To me, this all comes across as designing from a straight male's perspective. The male animations are practical, the female animations are cute (footsie) and "sexy".
So don't equate the two of them. A lot of people also mention comic book's muscle bound male heroes. Once again, it is not the same because they are not designed to look sexy to the designers (who are mostly male and probably mostly straight) and the audience. They are designed that way because of the tough, strong, practical, cool and power fantasy factor.
