In college, stuttering bad in a presentation
When I wet my panties - twice - as a kid. Once when I was three and did it right in front my mother after she'd just asked me if I had to "go" and I said "no" (I got spanked for that) and when I was six and did it in class (we dried them on the teacher's bathroom radiator and Mom never knew until years later when I was too old to spank!)
kicked in the balls and dropped by exwife, in front of her sister, and a friend of her's
Caught by a friend while having sex.
