Indeed. We might decide that evidence suggests that x is bisexual, but in the end only x knows. I just find the idea of Hawke's sex deciding their friends' sexuality kind of silly, even if it's just video game.
But Hawke's gender doesn't decide or define the sexuality/sexual identity of the companions. From a mechanics perspective, you have 5 LIs, 4 of whom are available to Hawke regardless of gender. Two companions make comments to Hawke that could be interpreted as flirtation - Isabela and Anders. With the former, the comment is in a cut scene and the player does not get to react/respond. In the latter, the player can respond (I don't want to go tangential with how Anders was handled however). Going back to what other posters have said, Fenris's comment, while you are allowed a heart-icon reply, doesn't really ring as flirtation, but this can be open to interpretation.
It takes the action of the player to initiate and follow through on a romance. Those afore-mentioned 4 companions, while always available as LIs to the player across
multiple playthroughs, are not necessarily bi-, straight, or gay. They are subject to the interpretation of the player, and how he/she wishes to play Hawke. They don't really mention former lovers (save Isabela and Anders), but that doesn't mean that they didn't have previous relationships, nor does the Hawke they are with determine or somehow create a default for who-came-before. I always saw the companions as responding to who Hawke is - the sum total - not just Hawke's gender. While we could get into the psychology, physiology, and biology of how attraction is measured, when it comes down to it, love is a mysterious thing - and we don't always know beforehand, like some checklist, who it is that we may feel love for, and to what degree. I think the companions were written in that light - Hawke just happens to be that one person that all the lights and bells go off for. But only if Hawke (and the player) puts forth the effort.
