12 and up? some people haven't hit puberty yet. my Gawd i hope you youngin's in here not having sex. you know how many pregnant teens are 13 when they have kids.. i hope folks got information before hand. and 16 is STILL young, a lotta people do NOT mature when their 16. Some people don't mature until they are 21. I know many guys and females. But it depends on what you mean as "mature".
