Bloody : Bloody discharge from the penis could occur as a result of trauma or a medical condition. Throughout the genitilia, there are many areas and blood vessels that could be broken, leading to blood in the urine or semen or bloody discharge. Items that could cause trauma and bloody discharge from the penis could be aggressive sex or masterbation, interrupted sex, kidney stones, prostatitis or a procedural biopsy on the testicles/kidney/bladder. Medical conditions that can cause bloody discharge from penis include: side effects of blood thinners, stds such as chlamydia/genital herpes/warts, prostate cancer or bladder cancer.

See below : Bleeding from the penis, and not present in the urine, implies either the prostate or urethra as the source. Assuming absence of recent trauma, most common cause, often after straining, would be a ruptured vein of the prostate seen most commonly in older men with an enlarged prostate (BPH). Urethral stricture, inflammation, infection, prostate calculi less common causes. Recommend GU evaluation.
