A recent study showed that sexuality might be genetically determined.. Though it was only tested on mice here, if it works the same for humans, it could revolutionize the way we look at the whole "sexuality = choice" debate.
However, I'm not ruling out that specific factors also play a role on it, though I do think our current understanding of that is severely limited.
