Hello, Normal penile discharges are pre-ejaculate and ejaculate, which occur with sexual arousal and sexual activity. Smegma, which is often seen in uncircumcised men who have the foreskin of their penis intact, is also a normal occurrence. However, smegma, a collection of oil and dead skin cells, is more a skin condition than a discharge. A variety of conditions produce male discharges that aren’t considered normal. Because your discharge is yellow, Therefore I suggest consulting a urologist for physical examination, diagnosis and treatment. Hope I have answered your query. Let me know if I can assist you further. Take care Regards, Dr. K. V. Anand, Psychologist
