fight/flight instinct is a "immature instinct" for most people 99.9+% it's not controllable.
and more likely to make mistakes..
might as well be panicking since it's the same damn thing.
I can control it and trigger at will... which is uncommon...
I would have to disagree with part of your statement, I will agree that if you can control and trigger it at will you are uncommon.
But the instinct itself is not immature, it is a survival instinct and it goes much deeper than just whether you stand your ground or flee, AND it has a lot to do with how our bodies internally and chemically react to any circumstance that affects our safety. Your testosterone level has a big part in how your body is able to react. Can you mentally learn to override some of that, I would say its possible.
But Take a football player in a hot practice this time of year, As core body temp starts to rise and the body senses the body intensifies the use of blood to the organs as a cooling mechanism, much like the coolant or radiator fluid in your car At that point is would be almost impossible for that player to get an erection. If he continues on in the heat beyond what his body can accommodate cooling wise, the most oxygenated blood will not flow as freely to his legs and arms, thus becoming too week to continue running and practicing in the heat, then it can get reduced flow to the brain and head causing blurry vision and/or dizziness. This inevitably end in a heat stroke. But the bodies ability to keep us going thru short term dangerous situation from us pushing ourselves past what is safe to a true threat on our life all starts from the chemical reactions in our body instigated by the bred in "fight or flight" instinct which starts with a surge of adrenaline. Adrenaline levels are directly affected by our Testosterone level.
Why is this relevant? Like the wrestler I was speaking about above, When he is on the mat in a fight , not for his life but for his pride, adrenaline is pumping and his body is directing all the fully oxygenated blood is can to his muscles to help him perform, there would not be any excess available for an erection.
Now, if at some point the wrestler starts believing he has the match won and thus there is no further threat or he gives up on winning, then his body follows suit and adrenaline levels come down freeing up testosterone and blood flow to do other things, in those cases an erection is very possible and is some instances even likely. especially being that at that age sex is so important in our minds and ranks a very close 2nd to our safety most of the time.
