These days, many teenagers are in relationships just because they want to raise their self-esteem, not because they actually love the person they are with. Why, in your opinion, they choose to raise their self-esteem by having unnecessary relationships instead of raising it by other methods?
Some are in love and to be honest there's pressure these days to be with a boy, loose your virginity ect. I don't think it raises self-esteem in the relationships I've been in but I guess it depends on the person and they like the attention there given ect.
