However I don't believe the bible mentions women on woman sex anywhere.
Romans 1:21-26 (Written by the Apostle Paul)
21For although they knew God, they neither glorified him as God nor gave thanks to him, but their thinking became futile and their foolish hearts were darkened. Although they claimed to be wise, they became fools and exchanged the glory of the immortal God for images made to look like mortal man and birds and animals and reptiles. Therefore God gave them over in the sinful desires of their hearts to sexual impurity for the degrading of their bodies with one another. They exchanged the truth of God for a lie, and worshiped and served created things rather than the Creator--who is forever praised. Amen. Because of this, God gave them over to shameful lusts. Even their women exchanged natural relations for unnatural ones.
"I don't believe the bible mentions women on woman"
Romans 1:20ff, For this reason God gave them up to their vile passions. For even their woman exchanged the natural use for what was against nature." NKJ
It bans sex between people who haven't had their union blessed by God. Hetrosexual or homosexual. No such unions are blessed. God doesn't bless sex outside of marriage. His definition, not some legislator or judge. None.
