While having sex, blood is coming out of my penis. Its happening from past few weeks. earlier everything was fine. Whenever blood comes out during sex, i usually check it and find that during sex whenever my skin goes down there is minor stretch of inner skin and there is minor cut and blood comes out. I then wash it and within few seconds blood stops coming.I donot experience any pain. Its just that during sex it happens whenever my skin goes down cut happens and blood comes. I have already visited a doctor and he said there is nothing to worry.
