Very true, Damian. Your concern for the semen retention is praiseworthy. Indian Rishis and Yogic gurus had understood semen's vitality long ago. And so introduced 'Brahmacharya Ashram up to 25 years only for the purpose of preserving this vital power. You have lived in the company of some spiritual master at Rishikesh in India. That's why you understand the subject very well.

Thank you for sharing such precious thought which has also scientific justification.
