I hadn't turned on the water yet, so I was able to see my semen when it hit the floor. I noticed that there was a small amount of blood that came out with the ejaculation-- it was mixed in with the drops of semen on the shower floor. I don't seem to have the same problem with urniation ... I checked my piss in the toilet earlier and didn't see any blood. (I do however realize that hematuria can be invisible.) So I'm wondering if I should go see my doc right away, or if I should wait a while. Has this happened to anyone else?
