I've had rotten guts my whole life. In my mid twenties I'd had enough with the constant pain and... uh... well other icky stuff. So I went to get checked out. They were going in from both sides and I was obviously concerned about my virtue as seems to be the worry here. The drugs they supposedly gave me had absolutely zero effect (they said I would need to wait a half hour or so after and then have a friend pick me up because I'd be so out of it). I was as sober as... well a totally sober guy. They did the "bad" scope first which was certainly not pleasant but not as big a deal as I thought it was going to be. I thought the worst was over. Then came the gastroscope. That was HORRENDOUS. They just rammed that mofo right down my gullet, choking and sputtering be damned. Hard to believe but that was a hundred times more violating than the "bad touch" exam.
The "prep" for those tests was however the worst part of the whole experience. The word "raw" took on a whole new meaning after the cleanse.
I swear though... I think they must have given me a placebo or something instead of the sedative just to mess with me. Probably thought I was a drug seeker or something. Yeah, I'm such a hardcore buzz chaser that I'm willing to get treated like the focal point of a Nine Inch Nails video just to get a fix.
Point is... the ole finger thing will probably be much less traumatic than you think and it really could save your life and/or manhood. I know an old guy who got prostate cancer (probably from being too proud to get checked out) and... well now he can't do that manly thing us manly men like to do. Still saved his life though and he might make it to 90 the way things are goin'.
Good health to you, Beags.
Oh... and it turned out that I was okay. Just too much damned stress and a bad diet. Still got shoddy plumbing but I can manage it.
