Suddenly after years of no problems masturbating, last night and this morning, my ejaculation contained what appeared to be more blood than semen. There is no pain associated and there doesn't seem to be any blood in the urine. what is going on!?!?
Blood is not normal in either the urine or ejaculate. If it continues more than just a few days, you should see a Doctor. I can't tell you a list of possible things which might cause this, but do you really want to chance that something serious is going on here?
