We are not limited by our anatomy in all things. We are more than our bodies. Expressions of love and fun have a great deal to do with our humanity - we are more than animals. And that is what is missing from the view of sexuality expressed by the Church - the limitation of sexuality to procreation only when it is also a function of emotions, of love, expressing love, and enhancing bonding.

I do argue for sexual boundaries- when it comes to force or children. And, I do believe in sexual faithfulness in marriage. But God made the LGBTQI person, too, and God does not make mistakes.

I do not know at all that God has made clear what He wants from us, other than to love Him and love one another, be kind, helpful, respectful, honest, and all kinds of ways in which we show care and concern for others.  

God made us to learn and grow, to evolve, to reached beyond established knowledge. If He didn't, we would still be in the Stone Age.  Be open to what we discover; we never have been perfect
