Can I sound totally naive for a minute?
I remember my mom took me to this thing at the library when I was in like 3rd grade, that talked about girls and puberty and how everything that happens to your body is OKAY.
Well I remember them talking about pubic hair, breasts, periods, tampons...all the great stuff. So I was totally confused and told my mom I had my first period because I thought it correlated to getting hair down there.
I was so embarassed to find out that I was wrong. LOL!
