Yesterday I found blood traces in semen during ejaculation. It was present initially but after that normal semen came out white in colour. To confirm I tried once today and found blood again in semen. Blood was only in the initial part of ejaculation. There is no pain during ejaculation or urine or stool. Also no blood, itchiness etc is found during Urine or stool or ejaculation. Urine, stool are all normal in colour. There is no pain in lower abdomen or testicles either. Please help and guide me. Is this something serious to be worried about? Please help
