Physical age is not as important as is mental and emotional maturity. Though around sixteen or so, is an average figure. Some dates are not all that serious anyway. It's mostly to fit in with the other kids that are dating. It's mostly recreational. Though caution is always needed. My oldest didn't start dating till she was 19. She just wasn't interested in boys. My youngest has always been attracted to boys, and the boys flock around her. Though she's 16 she's just having fun. Nothing too serious. She wants to travel and not be bound to a 'boyfriend'. For her it's just social, and to go hang with her other friends.
