I was having sexual intercourse approximately 60 hours ago. I am male. After approximately 15-20 minute, the urgency to ejaculate came upon me and to prevent it, I withdrew and changed positions. When doing so, I small amount of ejaculate (semen) was discharged. I continue to have sex but slowly lost my erection and stopped. During the next 24 hours a small amount of pinkish semen-like would discharge from my penis during urination (less that 0.5 seconds) and during the next 24 hours it appeared to clear up. In the last 12 hours it has somewhat reappeared, but not as bad as before. Also, my left testicle is swollen (similar to "blue balls") and painful. It occurred approximately 24 hours later (after sex). It is still swollen and painful, but appears to be improving. Do you know what has occurred and will it improve without medical attention?
