hey SC, i've actually had that done to me when i was 16... four times... its not bad, except the nurse's assistant shaves the area, then the nurse takes a turn, then the lab tech tries to shave closer, then the surgeon tries again
either way, its not too bad, i never had to spend a night in the hospital, you're lower area will stink of iodine for a week though... they couldn't conk me for any of the procedures, but most people get drugs and sleep through the whole thing.
