LOL I had to laugh when I read the comment about finding out everything in New Jersey. I grew up in NJ, and believe me, I knew NOTHING. My mom was afraid to talk about anything that happened "down there". And as far as I could tell, my friends were all in the same ignorant boat. We passed around a LOT of bad information! When I found some of my mother's pads in a closet, she told me that they were "for women who don't want to have a baby." Good thing I didn't end up thinking they were some sort of birth control!
I applaud you for talking to your daughter. I have only sons, but because my husband just crashed and burned trying to talk to them, I talked to them myself. We really never had one big discussion, but rather lots of shorter discussions from ... well,. geeze I guess from the time they could even participate in a conversation. But around 5th grade or so, I talked to them about what girls go through, because boys really need to know about menstruation, the female reproductive system, etc. I think a lot of parents of boys don't think that's important. But I kid you not, I had to explain to my husband AFTER we were married, what fallopian tubes and ovaries are. I vowed then and there not to send any men into the world as ill-informed as he was!
