Is the repentance of the passive party who was an ignorant child at the time of the act of sodomy accepted, and who now feels despair and hopelessness about the acceptance of his repentance?

The act of sodomy is a grave crime and a great abomination. However, if it occurs to a child before puberty, there is no sin upon him, due to the hadith: "The pen has been lifted from three: from the sleeper until he awakens, from the child until he reaches puberty, and from the insane person until he regains his sanity." Therefore, there is no blame upon you and no deficiency in your masculinity. It is not true that there is no repentance for the one on whom the act was committed, for Allah forgives all sins, and "The one who repents from a sin is like one who has no sin."
