A new survey published in the journal "Pediatrics" says kids are having sex.  Shocker, huh?  The shocking part is that even younger children are admitting to it.  Survey says:

33% of 16-year-old are sexually active.

71% of 19-year-olds are not surprisingly having sex on a regular basis. The shocker is:

2.4% of children by the age of 13 admit to have been sexually active already in life.  That's before becoming a teenager.  So, if you're a parent, you may have to have that awkward conversation much earlier than expected.  I wish you luck.
