Bad sites?Am not quite sure but I think you mean good sites for teenage dating.
First am pretty sure you're not done with school yet. Why don't you put focus on your books first,make hay while the sun shines,then the rest of the things like dating will follow.
Besides, at times we have to understand that this is another err,generation Y.OK I'll suggest you should not go for any online dating sites because you will meet different kinds of people. They might seem so nice but most of them are fake,starting from their identity.
If you really want to date just find someone offline, someone you know better and whose real.
