It's not a sin to have feelings that are not ordered by God... it's a sin when we act on them in thought, word, and deed.
Hmmm. I am not a male, nor am I a female. I am an ever-living spirit, and my body is not me, it is clothing for me, a spirit, for my duration on our planet Earth. Everything all that I feel during my stay on planet Earth, is felt only in my brain, this includes all that we eat and drink. And this happens through the nervous systems, which send electrical charges to various destinies to the brain according to receptors that have their proper spot in the brain, be it pleasure, be it pain - such as us accidently banging a hammer by their thumb. Pain gives us warnings to fix bodily damage.
Many a Soldier, who lost a limb in battle, still feel the missing limb as if it is still there. Why? because the nervous system has only been removed only up to limb by the amputation performed, lets say a leg amputation just below the knee. However, the nerves that went to the now missing portion leg and foot below the knee, still go to the brain, and these nerves sends a message in the brain that, let say the missing foot, the brain will receive the electrical charge from the foot, and the amputee who is missing that foot but will feel an itch in his foot that is no longer there. So, everything we feel is felt only in our brain. The brain tells us where in the body it was suppose to come from.
A few decades ago, Doctors and scientist did experiments on people who suffered breakage of their top of their skull. This gave them ability to examine access to a hole in the top of brain, very difficult to get to, the pleasure spot. They had a dozen or so patients male and female. Each one felt terrific and kept pushing the button that release an electric charge. One patient pressed the button sending the electric charge to the pleasure center of the brain 1500 times before the doctors turned off the apparatus and took it away despite his protest.
In the Old testament, several popular men of God who did have sex with same sex. God did not punished them. The Mosaic Law required death for such a relationship. But no witnesses, the Mosaic Law required two witnesses, and none came forth.
