Use proper anatomical terms. Don't use euphemisms to describe body parts like a penis and a vagina. Understand that refusing to use the proper terms will only convey that you're embarrassed about the bodies God has created. Pray for the peace to be able to overcome whatever embarrassment you have. When appropriate, use humor to defuse embarrassment when you're talking with your kids.
If you engaged in sex before marriage, don't avoid the subject with your kids. Don't neglect discussing the importance of waiting until after marriage to have sex, even if you didn't follow that advice yourself. If you were a virgin on your wedding night, explain why you're glad you waited and how God blessed you and your spouse as a result. But if you weren't, explain (without divulging extensive details) that your mistakes caused you unnecessary pain that you want your own kids to avoid.
Help them feel close to you and connected to your family. Realize that kids need to feel loved, and to have a strong sense of belonging. Don't leave your kids trying to fill those needs through sexual relationships. Affirm your love for them on a regular basis, and let them know their place in the family is valuable. Make the time and space in your life that you need to build close relationships with each of your kids.
Eliminate unnecessary activities from your family's schedule. Take them on dates to do fun things together regularly. Talk with them in the morning before your day begins and in the evening just before bedtime.
Show your kids that you're open. Let your kids know that you are always open to answering any question from them. Show them your interest and transparency through your facial expressions, eye contact, gestures, and body language.
Model sexual purity for your kids. Recognize that the way you live your life is the most powerful sex education lesson your kids will ever receive. If you're a dad, show how you remain faithful in marriage and treat women lovingly and respectfully. If you're a mom, demonstrate your marital faithfulness and treat your husband well.
Don't forget your opposite-sex children. Understand that daughters need their dads to give them the male perspective on sex, and sons need their moms to give them the female perspective. Give your opposite-sex children just as much attention as you do the ones who share your gender.
Teach them to resist peer pressure. Help each of your kids learn how to become his or her own person rather than defining themselves by their peer's reactions to them. Encourage your kids that they are each one-of-a-kind originals who are deeply valued by God. Motivate them to stand up for their convictions.
