Prostate secretions flowing out by themselves may be caused by over-excitement, penile stimulation or prostatitis. 1. Over-excitement: When over-excitement occurs, it often leads to brain stimulation, and prostatitis may produce too much secretion and flow out by itself. 2. Penis stimulation: The penis is a unique male organ that is often sensitive, and after being stimulated it is likely to lead to a euphoric reaction, causing an increase in prostate secretions, which can easily flow out on their own. 3. prostatitis: due to inflammation stimulation, often lead to the prostate mucosa congestion and swelling and increased secretion, it is easy to flow out. If the prostate secretions often flow out on their own, and accompanied by urinary urgency, urinary frequency and other symptoms, we should go to the hospital in time to find out the cause of the targeted treatment or treatment.
