What should I do to avoid engaging in sodomy again, especially since the one I engaged with in the last act is a minor, and how should I deal with this minor so that he does not fall into this matter again?

Sodomy is forbidden by the consensus of the Ummah and is contrary to human nature (fitra). Its corruption is considered among the greatest corruptions. Allah punished the people of Lut with a severe punishment unlike any He inflicted upon others. Nevertheless, Allah's mercy is vast, and Allah has promised His servants repentance and has promised forgiveness to whoever seeks His forgiveness. Therefore, the sinner must strive to proceed with repentance, fulfilling its conditions: remorse, the intention not to return to the sin, and abstaining from the sin with sincerity for Allah. If he returns to the sin, he must repeat the repentance tirelessly. This crime remains forbidden whether committed with a minor or anyone else, with the necessity of avoiding everything that leads to falling into it.
