Sucsessful and fun masturbation

I'm 13, I know I'm a little young but I find masturbation soothing and fun. I have no sex toys and know little about this but it works for me. What I do is cover my vagina in a thick layer of material (a dressing gown, coat or thermal underwear), Clutch the material so my hand is in a fist position, It works best sitting down on a cushion or sofa, Move your fist up and down while the other hand is rubbing various other parts, (boobs, inside of vagina, ect), I have been using this technique for almost six months and I find it very satisfying, I hope you do too!:)
