Fortunately it was when I was about twelve. On a school trip staying in Derbyshire I think, running from the showers with just a towel and dropping it and all the boys seeing my bum! Unfortunately for me there was a song at the time called 'hey fatty bum bum' this echoed around the school halls for a long time to come!
Thankfully I think that is it, I don't count childbirth, I was in agony!!!!!
Must have been 1995 when I was having my medical tests to join the armed forces. It was at a civilian surgery and I was asked to provide a urine sample. Instead of getting a discreet tube, they gave me a kidney dish which I had to carry the full length of the surgery, post sample, back to the Doc's office.
Did I mention I was in my shorts at the time, and not much else?
Talk about steady hands!!! :)
Im afraid mine has to be when i was out around the town, i got EXCEPTIONALLY drunk one birthday with several friends, so much so that i confessed my love to my GAY best friend, apparently wouldnt shut up aout it for 2 hours and ended up crashing at his cos i was so drunk i couldnt remember where i lived (recently moved!)
