Is repentance for perversion and sodomy accepted if the perpetrator is an adult, or is repentance impossible as stated by one of the fatwa websites?

Repentance from every sin is accepted if it fulfills its conditions. No matter how great a servant's sin may be, Allah accepts his repentance if it is sincere repentance, in accordance with His (the Almighty's) saying: "Say, 'O My servants who have transgressed against themselves [by sinning], do not despair of the mercy of Allah. Indeed, Allah forgives all sins. Indeed, it is He who is the Forgiving, the Merciful.'" And His saying: "And it is He who accepts repentance from His servants and pardons misdeeds." So, repentance is accepted for any sin as long as it fulfills its conditions: abstaining from the sin, resolving not to return to it, regretting having committed it, and that it be before the death rattle.
