Remember that you are young, and you’ll want to have a lot of fun.
There are other ways that you can go about meeting people your own age.
However, by looking at the sites which cater to teens you can meet many people you have more in common with and can have a lot of fun with.
Also, since you won’t be charged fees to become a member of these sites, you can join a few different ones and spend time on all the ones you like.
Having a dating site which caters to adults and minors is wrong on many levels and would definitely cross many lines.
However, you’ll have to find other means of finding that special someone in the mean time.
