My boyfriend and I have been having sex weekly but 3 weeks ago after sex, he went the toilet and noticed a large amount of blood and blood clots in his urine. This happened when he urinated several times after sex, the blood being less and less each time. Then again when we didn t even have sex, but he got excited the blood appeared in his urine. He has been the doctors and the doctor said to continue to have sex but it is not nice for him afterwards and is causing a lot of pain. He isn t in pain when he ejaculates or during intercourse. The doctor doesn t think it is an infection but could possibly be a weak or broken vein? If so, what could he do to solve it Thanks
