Anyone who thinks that any sexual practices between two women are prohibited is adding a new prohibition to the ones in
Leviticus 18.
1. man or mankind can be inclusive of woman. with woman being an extension and possession of man
Lev 18:22 Thou shalt not lie with mankind, as with womankind: it is abomination.
Gen 5:2 Male and female created he them; and blessed them, and called their name Adam, in the day when they were created.

2. Would man having possession of woman allow his helpmate to lie with another woman?
The following verses in NT gives me the impression that a woman lying with a woman is extremely unthinkable and against nature outside of the knowledge of God.
Rom 1:25 Who changed the truth of God into a lie, and worshipped and served the creature more than the Creator, who is blessed for ever. Amen.
Rom 1:26 For this cause God gave them up unto vile affections: for
even their women did change the natural use into that which is against nature:
Rom 1:27 And likewise also the men, leaving the natural use of the woman, burned in their lust one toward another; men with men working that which is unseemly, and receiving in themselves that recompence of their error which was meet.
Heb 13:4 Marriage is honourable in all, and the bed undefiled: but whoremongers and adulterers God will judge.
3. But I also believe our modern day society is artificial so it may not seem unthinkable or against the natural order at this time.
