I had another thought
I wonder if lesbian "sexual activity" might be comparable to men french kissing other men .
I can't think of a Bible verse that explicitly tells men not to French kiss other men.
"
You shall not lie with a male as with a woman. It is an abomination." (Leviticus 18:22 NKJV)
Clearly homosexual anal intercourse is prohibited, but it doesn't say anything about men standing or sitting and French kissing each other.
It's still a nasty, disgusting, worthless, stupid, and gay thing for men to do. We certainly wouldn't approve of it.
