Most men don't notice it, but, after a tooth extraction, they become temporarily impotent--an archetypal carryover from ancient times when wild animals and wild men measured power by the strength of their teeth. During these times they can counter their impotence by performing self-sex, but can exert themselves physically only after the bleeding of their gums has stopped and the wounds have closed.

Nature has a way of preventing men from overexerting their potency. It is from the ages of 25 - 35, the height of their sexual activity, when they need to have their molars extracted--the very teeth that literally and symbolically perform grinding, gnashing, and gritting.

Yes, we all have inborn safety valves, though we may not be aware of them.
