Why does my right testicle hurt after sex?

Pain in the right testicle after sex can result from various factors, such as muscle strain, epididymitis (inflammation of the epididymis), or testicular torsion. It may also be due to trauma during intercourse or issues related to blood flow and ejaculation. If the pain persists, worsens, or is accompanied by other symptoms like swelling or fever, it's important to consult a healthcare professional for a proper diagnosis and treatment.
