Soul... Seriously, I think what you are doing with your daughter is fantastic... you are making her know that she can talk to you about anything.
From my own personal experience, I was raised to have very very high morals, and to save myself for marriage. I always knew thats what I was going to do. The subject of sex was always based on a married couple when it arose in our household. And when I got to the age of being curious about boys, I knew in myself that I wasn't going to wait until marriage. When I got to a rebelling age, the first thing I did to rebel against my parents was lose my virginity. I was way too young, but I don't regret it. My mum knows all about it. She has since relaxed her thoughts and is much happier with the fact that we can talk to her about everything. It is often a strange experience to have sex discussions with Mum after being raised the way I was, but it is a good thing, and has been very beneficial to my younger sisters and brothers (who have each only had 1 partner).
So keep up the good work Soul, and please don't ever lose the honest, communication with your daughter... at least if something does come up, she knows she can turn to you for advice, rather than some inexperienced and perhaps immature friend.
