Very likely this 13 year old girl was raped by a male relative at an early age which lead her to become a lesbian.
Or she was seduced by an older lesbian neighbor or female relative recently.
Basically, 13 year old adolescents don’t suddenly all-by-themselves decide to become homosexual. An investigator or school psychologist should look into this girls past.
“An investigator or school psychologist should look into this girls past.”
Amen to that!
