What is the ruling on a man's feeling of inclination and lust towards other men since childhood? Is he considered among the people of Hellfire? What is the expiation for masturbation? Is it permissible to practice sodomy while maintaining prayer?

Sodomy is a major sin, and it is not permissible to commit it, even if the perpetrator is diligent in prayer. This is because true prayer prohibits indecency and evil. One must fear Allah and avoid falling into this sin. As for the expiation for masturbation, it is repentance from it.
