So after an enema (and yes, Harvey Korman's "Dr. Seward" from Dracula: Dead and Loving It was right, it does give one a feeling of accomplishment), I changed into a hospital gown, gave the doctor a small stack of color laser prints of funny medical memes I'd created, and climbed up onto a table (there were stairs alongside). I noticed some of the instruments, including something that vaguely reminded me of a dentist's lidocaine syringe, only with an extremely long needle. Flat on my back, with my legs in stirrups (he did have to make an adjustment to reduce the turnout: I'm not a ballet dancer!), and my privates lifted out of the way with a long strip of tape, I presented unobstructed access to both my perineum and my ass. Then a sonar head (in a condom) went up my ass, so the doctor could see what he was doing (unfortunately, unlike my colonoscopies, I had no view of the screen). He anesthetized my perineum, and while the lidocaine was taking effect, he demonstrated the snapping noise made by the biopsy needle. Finally, he began first using the lidocaine gun to anesthetize the prostate itself, and then going in with the biopsy needle. Over the course of some 20-30 minutes, he removed some 20-odd cores from my prostate, while one of the two nurses assisting him packaged them up for the pathologist, labeling them according to whence they'd come. The whole time, I was telling them stories about my previous medical adventures, cracking off-color jokes, and occasionally grunting in pain.
Then I got up, pulled on a pair of Depends, and changed back into my street clothes, and went to lunch.
I didn't bleed from the perineum for very long, nor out my ass at all, but with my prostate in a Swiss cheese state, I did bleed from my penis when urinating, defecating, and doing anything that put even modest strain on that area, so I was in Depends for well over a week. And I found that I was coming in unusual colors (there's got to be a very "blue" one-liner in that!) for well over a month. Thankfully, I'd been told to expect all of that, so it wasn't especially alarming.
