The distinction between feelings or inclinations on the one hand, and behavior on the other hand, is very clear. It's no sin to have inclinations that if yielded to would produce behavior that would be a transgression. The sin is in yielding to temptation. Temptation is not unique. Even the Savior was tempted.
The 19th century Mormons, including some of my ancestors, were not eager to practice plural marriage. They followed the example of Brigham Young, who expressed his profound negative feelings when he first had this principle revealed to him. The Mormons of the 19th century who practiced plural marriage, male and female, did so because they felt it was a duty put upon them by God.
We need to lay hold on the feelings and try to control them to keep us from getting into a circumstance that leads to sinful behavior.
Feelings can be controlled and behavior can be controlled. The line of sin is between the feelings and the behavior. The line of prudence is between the susceptibility and the feelings.
I think it's important for you to understand that homosexuality is not a noun that describes a condition. It's an adjective that describes feelings or behavior.
