People need to replace themselves obviously.
It's those that have the children they don't want due to not realising they can control sexual urge that I am referring to.
The human habit of enjoying self pleasuring activities, that's a problem.
We can control other urges including the urge to sexualise just about anything, we just choose not to.
For example breaking habits or addiction is a proven way that humans can adjust their behaviour for the better. Some need help but mostly, once a person has decided they will stop the behaviour, they can.
Your reply is naive and implies humans are slaves to their sexuality.
We do not have lizard brains?
