I have a 9 year old and 7 year old, both girls. My 7 year old has recently begun showing interest and curiosity in sexuality and relationships. I am a psychology major, so I am very aware that this is natural for the age. However, I received a call from a friend who stated that her 6 year old daughter was informed by my 7 year old daughter that boys have penises and girls have vaginas and periods. I told her that I had no doubt my child said that, since we discuss those issues openly in our family. My friend then went on to say that my daughter has been engaging in conversations that are "too heavy" for their age by telling her daughter that if she had a boyfriend she would lay beside him and kiss him. Should I be concerned by that? My friend seemed to think I should be. My daughter has no real knowledge of sex, other than reproductive organs, so I know that when she says those things, she is not specifically referring to sex. I also realize that it is a parents place to talk to their child about these issues, not other peers. I talked to my daughter and told her she is not to discuss those issue with friends, but how do I keep her from feeling ashamed to talk about sex and relationships?
