Thanks for asking that question. First of all, it is great you are thinking about taking with your teenager about barrier methods. Many studies have shown that conversations about sex, including condoms, do not decrease the age teens first have sex. What we know are these conversations help teenagers have safe sex if/when they choose. For more great information on talking with teens about contraception check out the advocates for youth website at http://www.advocatesforyouth.org/parents/143?task=view.
