Actually a new survey by The New York Academy of Medicine claims that over 40% of young teens in the US have lost their virginity by the age of 14. Even though its a scray thought, that is way more believable to me than 17 or 18 years of age. It just proves that parents today need to speak with their children at a much younger age. Even if you don't want, or think that they're too young, its better they hear what you have to say than to find out from their friends!
