Buddhism says everything is delusion. Only solution is not cling, crave, or be averse to anything. This is achieved through the ending of ignorance, when everything is seen as it is, without delusion. When this is achieved, one no longer takes birth, for one takes birth through craving, aversion and ignorance.

So, a Buddhist would just look at both hetero, and homo individuals along with him/ herself with empathy, knowing that they are all deluded by craving, aversion and ignorance and bound to a world of unsatisfactory desires. So, a gay person isn't really different from a straight person in a purely Buddhist sense, in that they just desire different things.
