I totally agree with the theories presented at the very top. I had notice some time ago the effects of masturbating and not masturbating, and true as it is on the fourth day it becomes really hard not to masturbate. All those testosterones are building-up and it must be releases however I have notice in m own body the changes that occur while I abstain from masturbating. I become more active, I exercise more, I also concentrate more and emotionally I feel better although I do go up in flames if I see a hot girl walk by, nonetheless my mood and stamina increase during the days of abstinence.
