In which case, you want your teenager to atleast practice safe sex. If you sense that your teenager has developed a soft spot for another boy or girl, casually suggest inviting him or her over with some other friends so that you can get to know him or her better. If you're lucky and your teenager is open with you about the way he or she feels about that special someone, then you can lay down a few dating rules. The first thing you need to do is to set a curfew and adhere to the rule strictly. They should inform you about where they're planning to go.
Money is another important issue that needs to be tackled.
If your child feels that he or she is old enough to be dating, then he or she has to learn that he or she has to finance her own social life. They should be budgeting for it in their allowance. Tell your child, whether boy or girl, that he or she must offer to contribute towards the evening out. If your son or daughter is going out on a first date, insist that his or her date come and meet you. It doesn't have to be a formal affair.
