It depends on the situation. We do know that gays, lesbians, and porn stars can be produced by childhood sexual abuse, but it is less clear that this is the only method of transmission. The subjects of this story seem to have become homosexual by taking prepubescent teasing far too seriously. However, victims often suppress trauma and do not think to consider it as a reason for acting out, nor do gay-friendly reporters wish to discuss such subjects.
Therefore, whether a homosexual teen will grow out of it probably depends on the level of trauma: actual abuse may be insurmountable, but peer pressure may well fade with time.
I feel sick. It is not natural of course....Shaking my head again.
