I feel weak and tired after masturbating.i know this is not due to actual loss of energy.i want some food and health tips to be energized/revitalized.

FItness: You're almost a grown man and learning about your body is important. After ejaculation, a man feels very relaxed and doesn't want to do anything else for a while; this will be part of connecting emotionally with your future partner. If it's really disabling or if you have an obsession / compulsion related to sexuality, get with your physician now; these things can be helped. Thanks for writing.
