My husband and I had sex tonight. When he reached climax, he had a dark discharge from the penis, like old blood. It was not fresh and bright red. He had to work at it harder and one place on the skin of his penis was a little irritated. We are elderly and as such sex is not often and somewhat awkward these days, but we were both shocked when this happened. I asked my husband if he was experiencing any inward pain. He said no, just a little soreness where the skin was a bit irritated.
