Brahmcharya is important for Grihasthi too. Langot helps here.
For protecting the Ojas, it is essential to wear. Always wear a Langoti or Kaupin or loin cloth during prescribed Brahmcharya period for Grihasthi, and you will not get inflammation or any other disease of the testicles.
If not possible daily due to modern life style compulsions, at least wear it during specific day/holiday. Saturday or Sunday or Both. Or on Vrat/Sadhana/Upavas time.
Swami Sivananada puts its importance this way:
“‘This Bandha and this Mudra have thousands of uses, and many varieties, too. Grosser the variety, grosser the use also. But, even the grossest form—a mere physical observance of Brahmacharya, has great utility. It will save many families from starvation, help to reduce the dowry-burden from the head of fathers of girls, and the school-fees budgets of many a young man.
‘The subtler forms have infinite uses. When this Langot Bandha is taken to the mental sphere also, then the practitioner’s brain-power increases, intellect is sharpened, and intuitive perception developed, too. When this Langot Bandha becomes man’s nature itself, then the Kingdom of God is opened to him and he becomes soon a great sage. Even the Upanishads and the Gita have sung the glory of this Brahma and this Mudra.” [1]
