Who had the bloody discharge? the male or the female partner?
Bloody discharge after an orgasm may be due to a simple cause like mild trauma after rough sex.
Or it can be due to issues like an infection in the urethra which may be sexually or non-sexually transmitted. A polyp, stricture or a stone in the ureter can also cause mild bleeding.
Prostatitis, which is inflammation of the prostate can cause bleeding in older men (over 50 years), although it can occur sometimes in young men.
In young men, a single episode of bleeding may not need any treatment since it can clear up on its own.
But in older men over 50 years, it should be thoroughly checked since it can be due to prostate problems like simple hyperplasia or due to malignancy.
