I'm fairly certain they explicitly stated at one point that Jack is from a point in the future where all humans are pansexual. I can't remember exactly when that came up, though.

They mention it within a couple episodes of him being introduced. They don't actually call him Pansexual, but they basically describe it. The actor, John Barrowman identified Jack as omnisexual in an interview though. 

@Vortex: Depends on what you mean by 'family-friendly'. Moffat has fingers in Torchwood and Who, and I'd say both have had extremely dark themes that I wouldn't really consider totally wholesome. Really, Nine and Ten are both often dark, heavily critiquing of society, and often explore the idea of the Doctor scarred by the Time War. Eleven was totally child-like for a while though, and I'm glad they went that route. Who should dance between dark and mythic. I definitely agree that it'd be nice to see some other perspectives guiding Who. When Moffat declared we weren't ready for a 'black or female Doctor', my love for him bottomed out. I'm ready for another lead if only for the possibility for that we'll see a non-Caucasian male Doctor sooner than later.
