Well, you mentioned pre-surgery jitters. You should be aiming to show up the morning of the surgery with a completely emptied and even exhausted prostate gland (just joking, but take every opportunity to enjoy sex). If you step up the pace, so to speak, you should clear the tubes quickly. Just 4 times since July probably isn't enough to properly flush out the blood. So, get at, with a partner or with yourself, but just do it!......
