I'm a teen (granted at the end of it but I still remember the early parts reasonably well) and I know for a fact I wouldn't go there. To build a teen advice sitw you need to really look at what kind of sites teenagers go on. Heres a few from my memory (sorry if they don't all work);
http://www.projectrockstar.com <-- a online games site for both genders, notice the colour scheme and layout
http://www.mykindaplace.com <-- a teen girl site woth advice etc. in it notice the neutral colours to it and use of whie space.
http://www.worriedneed2talk.org.uk/ <-- general site about teen problems, notice layout and use of white space.
