Question For moms with daughters

It seems like girls are having sex younger these days! Some of the posts I've read on here are from 14..15 year old girls having sex and as a mother to a daughter, this terrifies me. It makes me want to not let her out until she's at least 18.

How do you mothers with daughters feel about this? Is there anything I can do to "preserve her innocence"?

Sorry if I sound a bit crazy or old - fashioned or whatever but, it's my baby girl. . Even Some of the sh*t I see preteens wearing nowadays makes my eyes bug out of my head.

Too strict.. they rebel. Too lenient.. they might just do whatever they THINK is best. Where's the middle ground?

I'm just generally concerned about my baby trying to grow up to fast..
