How do i finger myself at the right way?

Okay, I'm 13 too! So what you want to do is start with ONE finger when you go in. Start with some rubbing of your clit and if it helps (which this normally does) watch porn! But yeah start with one finger, make sure that that finger is wet (you can use cream or if your in the bath just be careful ,that's how I started.) and GO SLOWLY! I know that it might be scary but its fine! And if this is your first time and you bleed, it's normal! Now when your finger is in, slowly start to move your finger in and out, casually get faster and harder. Hope this helped! :)
