I think teenagers should be focused on forming friendships, maintaining family relationships, and getting educated and ready for a career. Teens are still trying to figure out and decide who they will be in their life, and it's not a time to add the drama that naturally comes along with dating when you're too young. Messy breakups aren't healthy.
I agree here. Teenage years should be spent forming healthy friendships and maintaining family relationships. I wish my 15 year old self back then had appreciated this and not got myself into 2 particularly damaging relationships with slightly older guys :/ so, yeah. I really do see where you're coming from here, and I totally agree. I'd say from about the age of 18+ it's a bit more acceptable to date. But no younger than that.
