It actually seems kind of logical that fewer folk in the Star Wars Universe would be openly gay until after the death of Emperor Palpatine. Subtly in the Movies and far more overtly in the EU Palpatine was portrayed as someone who was severely prejudiced (to a Hitler/Eugenics level) against anyone who wasn't human, white, and male. Evidenced in the movies by the fact that the Imperial military consisted entirely of white men, while the rebel alliance had muppets and rubbermasks of multiple different types and genders. It follows then, that a: a bias against gays by the Emperor and the empire(with all that other hate on the table already) can be taken as read, and b: being openly gay made someone a target and being in the closet was far safer.
So there it is, an easy explanation why it never came up until now (in the new "Disney canon" anyway.) Again it's odd how it mirrors a universe that would exist sometime much later in a galaxy far away from it.
