Attraction and arousal are independent of a sexual partner’s physical genitalia. This is evident through sexual stimulation absent of intercourse, including self-stimulation. For this reason, I am unsure of why physical attraction is used to define homo- and hetero- sexuality. I do believe this is factor is not a worthy identifier of the label.
Emotional stimulation does not seem influential either. Although horrifying, orgasmic stimulation is possible during victimization.
There have been psychological studies conducted on commands vs. choice. For example: “Brush your teeth!” vs. “Do you want to brush your teeth before or after you shower?” The studies show that the option gives the individual autonomy and confidence, two things that we all desire. Sexuality is certainly an opportunity for autonomy. We are no longer forced to be our birth gender or marry the opposite (Command), but now have the right to autonomy (Choice).
Therefore, physical and emotional factors do not support either label, but mental influence does.
When examining religion and sexuality, different religions may have different codes of sexual morality, but they all have them, nonetheless. As a Christian, I submit to the Holy Bible as infallible and God-breathed. I am aware that sexual morality is that within Holy Matrimony between a virgin man and woman that continues throughout a monogamous marriage. The Bible identifies all sexual engagement outside of Holy Matrimony as sexually immoral. Therefore, the sin falls upon both those who identify as homo- and hetero-sexual.
So, is there an spiritual influence? Yes.
Behaviors are identified in Galatians 5 which explains Freedom in Christ and Life in the Spirit:
6 So I say, walk by the Spirit, and you will not gratify the desires of the flesh. 17 For the flesh desires what is contrary to the Spirit, and the Spirit what is contrary to the flesh. They are in conflict with each other, so that you are not to do whatever you want. 18 But if you are led by the Spirit, you are not under the law.
19 The acts of the flesh are obvious: sexual immorality, impurity and debauchery; 20 idolatry and witchcraft; hatred, discord, jealousy, fits of rage, selfish ambition, dissensions, factions 21 and envy; drunkenness, orgies, and the like. I warn you, as I did before, that those who live like this will not inherit the kingdom of God.
22 But the fruit of the Spirit is love, joy, peace, forbearance, kindness, goodness, faithfulness, 23 gentleness and self-control. Against such things there is no law. 24 Those who belong to Christ Jesus have crucified the flesh with its passions and desires. 25 Since we live by the Spirit, let us keep in step with the Spirit. 26 Let us not become conceited, provoking and envying each other.
Please, be careful not to fall victim to the snare of Satan by becoming judges. Biblical-Christian spirituality has less to do with sin and more to do with being Saved.
Jesus said that we must preach the gospel and be baptized. He said that then the Holy Spirit would descend upon us. When we ask Jesus Christ to be Lord of our lives, and receive the Holy Spirit, we then have direct connection with the Father. This divine order will lead us further and further from Acts of the Flesh, eventually seeing Fruits of the Spirit.
Therefore, if anyone is submitting to their flesh, please exercise full autonomy to choose life in the Father, through Christ, led by the Holy Spirit.
