IUD pain insertion????

I know alot of women have IUD's. I would like to know how the hell you could stand the pain??? My gawd!!! I've had 5 kids, a tubal ligation, tubal reversal and the pain from that didnt hurt like the pain from my gyno trying to put in the IUD!! I held on for as long as I could before I couldnt take anymore and had to tell her to get out from down there!!
