There are a lot of people out there that are just not comfortable discussing sex-even between other adults much less children! Seventeen magazine did an article on this subject and in it they found that teens whose parents are open and available for discussion are LESS likely to be doing it than teens whose parents don't talk to them! I started talking to my daughter about it when she was eleven and have gradually increased the depth of the conversations as she has gotten older! She even tells her friends that if they have questions that they don't feel right asking their parents that they can talk to me! I just have to add that she is almost 18, a senior this year, still a virgin and has DUMPED boys for pressuring her to "do the deed".
