I had that same experience, so I am guessing yes, it's normal stuff. My penis and scrotal swelling came with severe black and blue discoloration. It was scary, but not all that painful and had subsided in another few days, especially after the catheter was removed. My wife became much more knowledgeable about my genitals that first two weeks post op, whether she wanted to or not. And 6 incisions seems to be the standard with RALP. I am now five months post-op and still trying to get my stomach muscles back to where they once were.
