When I tell the parents of my 11 and 12-year old students that I'll be teaching their daughters about the clitoris, it's not uncommon for them to tense up and stop breathing.

If you had to tell your daughter - or any young girl - the most valuable pieces of information about her cycles, what would you say?

I bet that when you got your period for the first time, someone told you, "Now you're a woman" or "Now you can have babies."
