Modern psychology says they shouldn’t be consuming those videos, it mentally normalizes to t. They need total abstinence, possibly removal from any source of any temptation, and if need be chemical or physical suppression of their desires.
Additionally homosexuality is a normal variant on human attraction, the full equal to heterosexuality not just culturally but in the eyes of psychology. Pedophilia is now understood to be a deviation in psychosexual development.
Additionally spreading csam in right wing extremist communities isn’t necessarily an expression of desire but at times is done to trauma bond members

There is no safe or healthy outlet for those desires.
