"Why are we here? Where do we come from? Where are we going?" I remember when the missionaries asked me these questions as an investigator. I told them that I came from Heaven, but was going to Purgatory. They didn't think it was very funny...
As members of the Church, we believe that God was once mortal... He was like us. We believe that the ordinances and covenants in the temple will allow us to become like God in the afterlife. Once we're like God, we'll make little spirit babies, and we'll live happily ever after, as we send our kids down to mortality and listen to them bitch and moan at us for stubbing their toes and losing their keys.
That's the plan. Be like God.
What if you're gay? If you're gay you need to reevaluate everything. "Why are we here? Where do we come from? Where are we going?" The answers we all have been taught in Church... well... they simply aren't applicable anymore. They aren't going to happen... at least not as the Church teaches us.
How did Heavenly Father and Heavenly Mother make us? How do we, when we achieve Godhood, create our own spirit children? In Moses 3:5 we learn that God created all things spiritually before they were created physically. He created us, and therefore we will create our own. Will I be literally birthing out babies? Ummmm... no. I'm not going to be doing that in mortality... much less for the rest of eternity. And the word create isn't exclusive to spirit children... it extends to things like planets and trees. Will I birth a planet? Fuck. No.
There is so much about the next life that we simply don't know. We don't know how we will make spirit children, or how eternity will be. Trying to say that homosexuality is not natural and not ordained of God by saying that you have to have a man and a woman to physically make the child, is idiotic at best. Heavenly Father would have had to have an eternal stash of little blue pills, and Heavenly Mother would have had to have a really high pain tolerance... and an ironclad vagina. It simply isn't logical.
And even if this is the way it's supposed to be... if the Plan of Salvation is really full of misogynistic doctrines and ideals... how ridiculous is it that Heavenly Father gets pleasure and power while Heavenly Mother gets pain and stretch marks? I mean... it is such a small price to pay to spend an eternity having your children, at worst, have no idea that you exist, and at best, feel you are too sacred to brag about...
