I have hard orange tiny grains in my semen. Only happens every once in a while. I have looked online and there are doctors(non-urologists) who say it might be blood(likely from the prostate). They are only slightly uncomfortable and are mixed withing the semen not particularily before or after but inside it. Only about two to three and of verying color from slighlty tinted yellow to full blown orange(like the water stuff from scabs that hardens..its color). I personally think it is aged old semen because I have no blood in my urine or any other symptoms. And the fact that there are stages with different colors to me significantly lowers the chance of it being blood. If it were blood I don't think there would be such drastic variations of the color. But I am not a doctor.I do have a testical that is lower thant the other and I know that is an increased chance to cancer. I also had a cyst a while back when I was fourteen (23 now) and I think there is one more again but it is near the tip not the testicles. I have been drinking a lot of tea lately but also water, I just recently(week ago) worked very hard in the california sun and was constantly drinking water and my urine was still yellow(normal color yellow). I eat pretty healthy, although I have been drinking lots of homemade sweet tea and a lot of milk. I used to get bloody noses a lot(randomly) as a teen but haven't since I was eighteen. Well that's all the relevant information I could think of.
