Every teenage girl goes through this stage in their life..Most of them decide to just "do it" out of curiosity and uncontrollable urges...basically cuz they're so vulnerable and young. Whatever you decide to do, just know it all has consequences, always be careful...
I would suggest experimenting with yourself, just take it easy...
You will regret having sex before 16, i assure you that...even then, I'd hope when you do it's with someone you won't regret later on either..
btw...as soon as you start masturbating, you're most likely going to want to have sex, so I'd suggest try to control your hormoes as much as possible.
good luck*
