When Is The Right Time?

Parenting has got to be one of the hardest gig's in the world.  No paid vacations, no sick days, some of us don't even get flex time (shout out to the single parents.)  It doesn't help that television and technology exposes kids to things that mature them way too fast.  Sexting and Textual Harassment are terms that were born just this decade but already have been a serious issue.  And no matter how many times we (grown folks) say once u send a pix there's no telling where it ends up, I BET you we still sending risky pix to loved ones. Im guilty of it, but I don't ever plan to run for office so... :P But seriously, kids have WAY too much access to the Net.  PS3, Cellphones, Laptops, and computers in their bedrooms! And yall wonder why little Suzie has a Youtube Video of her dancing on a chair?  Webcam attached to the bed, and facebook page 2500 friends deep.  And parents ALLOW THIS to happen.
   My oldest daughter is 11 yrs old, and getting to that age where she is blossoming and definitely "smelling herself".  Pretty soon she will be a teenager and I can only pray that she doesn't do half the crazii shhht I did as a teen.  But I know to be ready for all sorts of drama.  In efforts to prepare myself I have been asking other parents when is the right time for certain things like Facebook page or even having their own computer.  In my house there is one computer and it stays in my room.  This way I will always know what goes on when they are online.  Some of my children's friends and cousins have FB pages already.  I think 15-16 yrs old is a good age for a page, but I'm sure my husband will disagree.  Never is most likely his answer, lol (protective daddy)  When is the right age for a FB page?
    An even harder question is when do you discuss Birth Control?  By the time children begin high school sex has already been a topic of discussion (or activity) amongst their friends. If your 14yr old daughter told you she was thinking about having sex (still a virgin) would you put her on the pill?  As soon as my mother found out I that I lost my virginity the first stop was the local clinic.  I got the full STD check and was put on BC pills instantly, age 15yrs old.  It did not make me have more sex, but it did make it easier to say "yes".  Some parent feel if you give them protection then they will have sex more often.  Other parents feel that safe is better than sorry.  What do yall think?
