Is dating good or bad

There's nothing wrong with dating as a teenager. People date, have sex (casual or not) fall in love, break up, get their feelings hurt, but without lasting damage.

But the same issues that sometimes occur in adult relationships---emotional or physical abuse, sexual assault, cheating, STDs, unplanned pregnancies--do occur in some teenage relationships. Many adults find it difficult to deal with one or more of those circumstances; teens who have less life experience and and intellectual resources are left even worse off in how to deal with them. This is especially true when they feel, for whatever reasons, they cannot confide in their family (and not all families are loving and supportive).
