Wrong. Even if they have sex with someone of the same sex they may not be homosexual. This happens in prisons all the time, is well documented and researched. Most of these people who have sexual contact with folks of the same sex are heterosexualI don't think it is right to say that a youth is a homosexual because he has feelings for someone of the same sex. That may pass. It may not. Only the behavior ultimately determines whether a person is a homosexual.
You are wrong, yet again.
