In my case it was 16. However, I have friends who started as early as 11 – one of them is 15 and pregnant, another has apparently done “everything but” and is currently 12. You need to be having the talk with them as early as 10 years old – before their puberty starts becoming a problem.

She was six months older. First time for both of us, we both reached happy endings.
You have a friend who a 12-year-old girl?
Not really my friend; she was just hanging out for a few days with me and my current girlfriend (who is the reason I know her).
