Whether God spoke through prophets or not is off-topic for this thread. If my child said to me, "Mom, I am gay," I would certainly not consult any prophets, as they don't know my child, and they don't know my family. I would say, "Darling, I love you, and I will do everything I can to support you and care for you whatever sexual orientation you are or how God made you."
There is a great song writtten by Fred Small whose chorus goes like this:
"You can be anybody that you want to be
You can love whomever you will
You can travel any country where your heart leads
And know I will love you still
"You can live life alone
You can gather friends around
You can choose one special one
And the only measure of your words and your deeds
Will be the love you leave behind when you're done."
