Why would a man bleed from his penis after ejaculation?

42 year old had not had sex for a while ,when had sex and when ejaculated was painful to ejaculate then saw bleeding from penis after ejaculation
There are several different potential causes for this problem, but you should definitely get in to see your primary care doctor or a urologist for a more complete evaluation. The most likely cause is that you suffered some irritation to the urethra or to the prostate from the sexual intercourse. This is a relatively common complication, especially of vigorous intercourse, and it could be more likely to occur if intercourse has been relatively infrequent. If this is the case, then rest should be all that is needed to heal things up. There are other possibilities as well. For example, inflammation of the prostate, called prostatitis, can cause both painful ejaculation as well as some blood at the tip of the penis. Similarly hypertrophy of the prostate, which can begin to present itself in someone your age, might also be the cause. Your doctor will be able to perform a complete examination, include a rectal examination to see if the prostate is swollen, tender, or if it has any nodules that might require further investigation. Based on what they find, your doctor may recommend either a watch and wait approach or they might want to get some additional tests right away. Good luck!
