Converting "deviant behaviours" was a mainstay of psychological practices up until recently. It wasn't limited to sexual identity. Anyone who didn't conform to social norms of so-called 'morals' and religious background was subjected to this kind of torture, one of its more famous victims being a daughter of the Kennedy family.
There is no legal sexual abuse. There is lack of information, lack of evidence or complicit corruption. Any judge that respects the spirit of law will treat abuse as such when presented to them.
Yet if by chance, any abuse is legal then you are also allowed to perform it on those who practice it on others. I recommend you do so if there is such a situation.
