I can't think of just one MOST embarrassing, so let me share a recent one. I had a hysterectomy in 2011 that left my belly with a substantial scar. Runs from my belly button as far down south as it can. Consequently, when I'm at the health club, I keep my rump to everyone because I'm embarrassed by the scar. In retrospect, the hunk of toilet paper hanging out from between butt cheeks was probably more embarrassing.
Now if you'll excuse me, I must move to a land where no one speaks English and therefore cannot speak of my shame.
