There are many justifications offered to justify proscribing male orgasms. Men are depicted as universally licentious and depraved. A harsh and untrue judgment: there are many kind, faithful and good men.
Chastity gives loving men the control they are unable to maintain by will power alone. I.e., that preventing masturbation often makes the man – when release – a more passionate lover.
That chastity can be used to refocus men on useful tasks is surely true of lazy and thoughtless males.
The real value is not as a lifestyle enhancement.
Accepting a woman’s control of your sexuality and pleasure is true submission. A man who consents to be kept chaste seeks to honor and please the woman who controls him. He deserves credit.
Chastity is loyal and humble obedience to women’s authority.
