Hi everyone! I feel sorry to say that I masturbated 3 times to porn today morning, losing my 70 days streak of No PMO. I feel like I'm drained off all of my energy. I don't have the capacity to think or concentrate on anything properly now, and my physical energy is also diminished to a great extent. I have a question to all my friends here. That is, Why does ejaculation take so much of our physical and mental energy? Why do we feel so drained after we M 2, 3 or more times in a row. How does energy leave our body with the semen? And why can't we think or concentrate properly after we masturbate multiple times? Is there any scientific explanation? Can anybody explain?
