I think the most embarrassing moment for me was when I was about 5 or 6 years old, and I was at a crowded beach with my family. My parents were very cautious and protective, so when I used the bathroom, normally my mother would just take me, but occasionally if I was with my father, he would just take me to the mens room with him, if I needed o use the bathroom, and wait outside a stall for me. Well of course on this occasion when I needed to use the bathroom, my mother and sisters were out swimming, but I really needed to go, so my dad took me. The problem was that the beach bathroom didn't have stalls, just a long bench with 3 toilet holes on it, and this was a crowded beach, so there were about 30 guys in there, most of them changing, and a few using the bathroom. So eventually I have to take a crap right there in front of everyone, which by this age was extremely embarrassing to me, plus there were naked people changing into swimsuits everywhere. Very mortifying experience.
