Bob the Skutter I suspect that
USS Bones is worried about the people who wont see Jack as "omnisexual" they might just see him as gay.
Now I think even the must backward of folk, should be intelligent enough to recognise that he is not gay, and might use the term bi sexual.
I dont think is much difference between Captain Jack and a hetrosexual character like, dare I say it Captain Kirk, the only difference is that instead of just women, he "charms" anything & everything.
