25 They exchanged the truth of God for a lie, and worshiped and served created things rather than the Creator--who is forever praised. Amen. 26 Because of this, God gave them over to shameful lusts. Even their women exchanged natural relations for unnatural ones. 27 In the same way the men also abandoned natural relations with women and were inflamed with lust for one another. Men committed indecent acts with other men, and received in themselves the due penalty for their perversion.
The Bible calls it the following
Indecent Act
Perversion
Unnatural Ones (Unnatural Relations)
Shameful Lust
The Bible is clear on Homosexuality.
