I don’t think your going to have many gains with that theory. However, the psychology part is interesting. If someone is too eager and is not seeing any gains for a while and getting frustrated, here is a good way to think about PE. Don’t think of doing PE to make your penis bigger, think of PE as making your penis healthier. I have been doing PE for a long time and have read that if your are still getting your morning wood and erections throughout the day and night, then you have a healthy supply of blood going to your penis.
So if you don’t see your gains (which will come over time), just think of PE as a way to make your penis more healthy. Think like that for a while, look in the mirror one day and you will see that your hard work and dedication has paid off. So yes, psychology can play a roll in this. Good luck.
