Is ghusl required after every instance of masturbation for someone who masturbates two to three times daily, while taking into account not being noticed by family?

Ghusl (ritual bathing) is obligatory upon the emission of semen, even if it occurs multiple times a day. It is a condition for the validity of prayer. Omitting it without a legitimate Shar'i (Islamic legal) excuse is impermissible and is considered a major sin. Shyness from family members is not an excuse for abandoning ghusl. It is obligatory to comply with Allah's commands. It appears that the questioner is putting himself in distress by engaging in the forbidden act of masturbation. Therefore, he must abandon it and repent from it. It is impermissible to address the sin of masturbation with a more egregious sin, which is the abandonment of ghusl.
