No - there was (is?) a certain cache attached to age 16 - in North America, at least. Sixteen was/is the customary age at which you were eligible to get a driver's license, and was/is an age at which a few other more 'grown-up' activities might become available. For instance, when I was a kid, there was a local 'nightclub' that did not serve alcohol - but you had to be sixteen to be admitted. It seems to me that sixteen was often an age at which you could enter a higher level of sports competition, become a paid camp counsellor or be hired to do 'adult' work. When a girl turned sixteen, she was 'sweet sixteen'. (However, nothing to do with consent I agree).
