Hrm, let's perform an in situ experiment! Right now, get on the horn with the people in your world and announce that you're actually gay/straight, whichever is different than currently. Then live accordingly for a few years so we can see what changes!

The stakes: one upvote.

I'm bisexual.. So the opposite is bisexual? I'm fine with that.

Can I have my upvote?

I believe the "opposite," or at least the closest thing, would be asexual.

Well played! Yes. :)

Too bad you chose to be ignorant :/

The scientific evidence is not on your side, if you're interested in that sort of thing.

Too bad you chose to misread the comment :/

The choice is in your actions, not your feelings.

So you think gay people shouldn't act on their feelings?

I think gay people have control over their emotions just like everyone else and it doesn't automatically impact 100% of their lives.

Actually I would argue that the scientific evidence is highly controversial, incredibly ambiguous and in need of serious and systematic review.
