Like, assuming the younger party has had no sexual experience, if a nine year old girl and a thirteen year old girl were to engage in homosexual behavior, I feel the younger party would also tend towards homosexual behavior in the future.
Or, like with circle jerks out of curiosity. If the group of young boys held them once, but then they continued to perform them, because they feel good and not because they are curious, I believe the boys would tend towards homosexual behavior.
