Thank you for asking. I can understand the distress you are through. Your complaints are suggestive of premature ejaculation. Shilajith or other aryurvedic medicine are not known to be so effective. I would suggest you to consult with a sexologist doctor. With suitable medications and instructions the problem can be controlled.
Next Steps
Kindly consult with a sexologist. For more information and specific suggestions you can consult directly on practo.
