Why do you ejaculate when you are nervous?

My personal feeling is that your inner pressure is too great, and you are too concerned about things around you. Train yourself to be calm, face it with a normal heart, learn to take a deep breath often, look up at the sky more, go for a walk in nature more, and don't treat some small things as if the sky is falling.

Have time to see a psychiatrist and go to the hospital for a physical examination.

Don't be shy, it's nothing. This is normal.
