I have a question related to, but maybe not the same as the man with other concerns.  I am experiencing a similar situation in that for the last two times I have had sex, I have found blood in my semen.  also for the next hour after sex I do find blood in my urine as well.  I did go to a doctor and she prescribed an antibiotic (now that I've read more, I think she is just hoping to rule out prostatitis.  What really concerns me though is that 8 and 5 years ago a similar problem occurred.  I was married in the meantime ( for 4 years) and so was not using condoms but during the time with my ex-wife, I never noticed blood in my urine or semen.  Now I am having this problem again and am using condoms so, of course, my first question is whether this could be related to my use of condoms, maybe an allergy--though I do not know how latex allergies present and manifest.  But my real fear is that I may be dealing with cancer and have been poorly diagnosed for years.  I would just like to know what tests I should demand so that I have not only the best information but also the most informed decision about how I should move forward.  I am 39 years old and have no health insurance but I will pay for as much as I can to help myself.  I will admit  that I am very scared.  Any information you can provide will be very very appreciated.  Thank you so much for any any and all help you can provide.
