If you are so afraid or too embarrassed or too immature to have an open adult dialogue with your parents about sex then you have NO business f*cking!!! My parents failed to do this with my older sister who got pregnant in high school and hid it from the family until her last few months. They made sure I knew about baby making and venereal disease and got on birth control at an appropriate age. What is an appropriate age? That has been debated by religious and parent/teacher groups for years. I recommend operating on the "old enough to bleed, old enough to breed" paradigm.
Upon a girl's first menstruation it is imperative that parents have a discussion about dealing with blood, birth control, and venereal disease. Let's face it, being a girl is disgusting and it helps to have a good home support system. Parents should have the talk with boys when they start getting "morning wood" and "nocturnal emissions." It is up to the parents how detailed they want to get and if they want to take the mom tackles daughter, dad tackles son on the talks. They also need to agree on rules for dating for their children and please allow them to take the health course at school that goes over reproduction and social responsibility for their offspring. It seems this education has been lacking on all fronts worldwide.
Knowledge is power and with the potential to make a baby teens should have greater responsibility and knowledge for planning a baby at an appropriate time in life instead of having one and dropping it in a dumpster or using it for a welfare check. I guarantee many of your children are having sex and not telling you about it. Make sure you have a good little sit down chat. If you are uncomfortable with it there is a Planned Parenthood where you can make an appointment for your child to talk to a health care professional for any questions they are uncomfortable asking you. Let's take the fear out of growing up and bring RESPONSIBILITY back to our baby-making!
