Penile discharge may be watery (clear) or cloudy (containing pus). The discharge may also be bloody. Urinary tract infection (UTI) or a sexually transmitted infection are common causes of penile discharge. Penile discharge is often accompanied by pain or burning during urination and a need to urinate frequently. Itching can also accompany penile discharge. Chlamydia, gonorrhea, and Trichomonas infections are common infections that may cause penile discharge. Genital herpes rarely causes penile discharge.
