The Bible has already provided that answer. In 2 Peter1:2-3, " Grace and peace be multiplied to you in the knowledge of God and of Jesus our Lord, as His divine power has given to us all things that pertain to life and godliness, through the knowledge of Him."

The Bible calls homosexuality, fornication, adultery, lying, cheating, stealing, murder, anger, wrath, malic, etc. all sins, and it says we are to put off these things (Col 3:1-11), meaning stop doing these things.

In Col 3:12-18 it says, "therefore, as the elect of God, holy and beloved, put on tender mercies, kindness, humility, meekness, longsuffering; bearing with one another, and forgiving one another, if anyone has a complaint against another; even as Christ forgave you, so you also must do. But above all these things put on love, which is the bond of perfection. And let the peace of God rule in your hearts, to which also you were called in one body; and be thankful. Let the word of Christ dwell in you richly in all wisdom, teaching and admonishing one another in psalms and hymns and spiritual songs, singing with grace in your hearts to the Lord. And whatever you do in word or deed, do all in the name of the Lord Jesus, giving thanks to God the Father through Him.

There are other scriptures that speak about human behavior, but this is clear. GOD HAS ALREADY DETERMINED WHAT IS NORMAL.
