When I was about 7, a friend of my Mother's was looking after me for a day during the summer and she pantsed me in front of her 2 young daughters, both of whom were older than I was though. I never told my parents what had happened and I learned later on that she was a total slut and slept around a lot but at that time I was very shy and it totally marked me for years that she'd humiliated me like that in front of those girls.
