substance in semen

When I ejaculate, there are brownish specks in the semen. The specks do not look like blood and if I rub them into the tissue, they disintegrate pretty easily. This has happened several times now and it takes at least ten days to clear. Whenever the problem is about to come back, I feel almost like my semen is pausing and building up at the head of my penis before comes out, then it comes out with a lot of force which is sometimes almost painful. Once I ejaculated again after experiencing the problem to see if it would clear up and the brown specks were accompanied with blood. Now, sometimes there is blood with these specks and sometimes there isn't. Nothing I've read so far describes everything I'm experiencing. Could there be some sort of blockage, prostate cancer or is it a re-occurring infection? The doctor said my PSA was slightly elevated but didn't seem overly concerned.

Blood in the semen is called hematospermia. A urine culture should be performed to determine if this is due to a bacterial infection of the prostate. This may also be a cause of the rise in PSA.
