I have issues with a sore penis. The soreness occurs when I get an erection after I ejaculate, whether I ejaculate from sexual intercourse, oral sex or masturbation. This soreness typically lasts 3 or 4 days, but the pain returns once I ejaculate again at which point my next erection will be even more sore. The soreness is not completely unbearable as I am able to have have sex and ejaculate again. Lately, I've noticed that after a long erection sometimes when I receive the next erection I get the same pain in my penis as I normally get after ejaculating. The pain does not exist when my penis is flaccid. Please provide any advice that you can.
