Surely you must know, that when homophobic people talk about "shoving sexual identity" in their face, this is what it really means.
There are gay people who get attacked for simply holding hands, or hugging in public.
Perhaps you should think twice between using phrases like that, and be clearer in what it is you object to, and ask yourself, if straight couples were doing the same thing, would you have a problem with it?
I've just said that I have NO problem with it, straight, gay, or otherwise. What is it that I am not making clear here?
