hum... girls are much more mature than boys, especially in their teen.
If your question is: ' I am 13, everybody else is dating, should I date?' the answer is no, because I take it in 2 more years those people will also become sexually active.
If, on the other hand, you have met a certain guy, you like him, he's cute, clean, washes his hands often and is crazy about you, then... things are a bit different. The question is NOT comparing yourself to the standard, but making choices for yourself.
Theoretically speaking, 13 is young. I started dating about the same time, and then at 14 I got my heart broken, so maybe I went a bit fast
. Age has nothing to do with emotional maturity... just remember that if you're unsure about that, boys are even more immature...
