However, wouldn't you rather them use toys than boys? No sex before high school at least would be like the one rule if I had a kid, except for no killing/raping people. Not that I think a toy is necessary at 12... but I'm also a guy. I graduated at 17... so I was 12 in middle school. I probably started masturbating around then. Maybe even 11. Girls mature faster on average... and I feel like I started later than my friends and stuff. It's scary shit, but they're doing shit young these days. The Internet probably doesn't help slow them down lol. 

So basically, while I wouldn't be a huge fan of the idea, and would definitely tell my kid as much... I'd also be like, "Here's my debit card. Pick one if you feel like you really need it. Because no sex until high school, remember."
