Many teens are dating by this age and some enter into very close and passionate relationships. Your teenager may take his romance extremely seriously and is likely to react angrily to suggestions that he's experiencing 'puppy love'.

With all these new, exciting feelings, it's easy for your teenager to get carried away, both emotionally and physically.

Establishing an identity
Don't take it for granted he'll start dating a member of the opposite sex. In establishing his sexual identity, your teenager may explore different types of relationships. It's normal, and it's important for him to feel that he can talk to you about what he's doing and who he's seeing. If he doesn't feel ready for a relationship yet, that's perfectly normal too.

When love breaks down
Your teen may invest a considerable amount of emotional energy in a relationship and may lose interest in other aspects of life, including friends and schoolwork. This can make a breakup very difficult for him. He may become intensely depressed and may need considerable support. Accept that he is grieving for the loss of a loved one. Don't be afraid to seek help if his depression becomes extended or severe.
