question: Hi, Doctor, I am a healthy male of 50 yrs of age leading an active life as well as active sex life. About 5 yrs ago i remained without sex for about 20 days as i was abroad and on return one night after intercourse my wife discovered blood particles in my semen. Next day i visited my doctor and he had got all the clinical as well as pathological examination done, i also visited a urologist and after discussing my reports jointly they came to the conslusion that there in notinh serious and i was adviced to increase my sexual activities for some days and have to observe regularly about the presence of blood. Surprisingly the quantity of blood got reduced with each intercourse and after about one week it was clear. I was advised to remain sexually active or you can say not to put a big gap i.e. 10-15 days, if it happens i have been advised masturbation. After 5 years it happened again under the same circumstances. Is it a signal of a serious problem or is it a normal thing. Pl advise.RA
