Prepare yourself for this important talk by educating yourself about STDs first. You will have a much easier time conversing with your teenager if you are well-informed of the topic. Your teenager will also be more likely to listen if he/she can see that you know what you are talking about.
Go over every known STD with your teenager and make sure he/she is aware of how the STD is contracted and its treatment options. It is important that your teenager knows the dangers of STDs.
Show your teenager statistics that apply to his/her lifestyle, age group, etc. Your teenager needs to understand that STDs are real, and could happen to him/her just as much as to the next person.
Relate to your teenager by sharing a story about your life as a teenager, and how difficult it was for you as well to fit in. Let him/her know that you understand how challenging it is for him/her to stay away from sexual activity. Your teenager will be more willing to listen to you if he/she knows that he/she can relate to you.
Inform your teenager of the importance of practicing safe sex. Emphasize the importance of using condoms as the only preventative from STDs. While you are not encouraging him/her to be sexually active at a young age, you want your teenager to be well-informed and safe when deciding to become sexually active.
