Does This Shock You??!!?

It shocks me and saddens me that some girls lose their virginity aged 12/13. yeah, 12!!!!!! I'm 16, and don't plan on losing it until I'm in a committed relationship, and I don't know when that will be so I'm not going to set myself an age.....but some girls aren't even teenagers! they're children. Surely it isn't healthy? And one of the 12 year olds I'm talking about, my friend told me has become a star. surprising?
