one of the things i read is some traumatic events can have an influence. i can recall being embarassed when i was 5. my family was staying the night at my grandmothers. my grandmother knew i was a bedwetter and insisted on diapering me against my fathers will. when i woke in the morning i was wet and messy. i can recall my father telling me to get out of the living room because i stank. my grandmother then removed the diaper in the middle of the kitchen in front of other relatives. i can recall being very embarassed by it.
