I want to stop pleasuring myself

Hi I am 13 years old. I masturbate, but not with toys. My parents have toys but I don't use them. I use some maybe like a sharpie or the end of a razor(take the blade off), and rub it quickly up and down against my clitoris. I hold my breath until I start to feel good and then breathe but continue to rub yourself. You can do this in a bath or anywhere, just make sure you have privacy.
Good luck!!
