When was yours? What was the worst part? Do you prefer not to talk about it because it was too horrible?
I started at 9 years old so I don't remember much of it. Except that it really sucked that I was ahead of everyone else. I think the worst for me was starting the Red Death at 11. I didn't know what was going on (very sheltered childhood), so I just tried to hide it. Never occurred to me that "Hey, I'm bleeding. That might be bad. Will I bleed to death?".
In terms of traumatic-ness though, puberty was nowhere near the hell that was pregnancy and post-partum for me. Holy sheet.
