It's interesting to see how many girls started masturbating when they were little...me too! I started by humping my blanket, stuffed animals, and pillows when I was 3.
I started playing doctor when I was 4 with some other boys and girls in the neighborhood. At first, us girls would take off our clothes and the boys would stare and giggle (for some reason, they would never get undressed themselves). The boys started tickling and fingering our little hairless pussies later. I started getting really turned on by showing off in front of boys (I remember getting in trouble in kindergarten for lifting up my dress and showing off my panties to some boys.) Eventually, us girls started playing these games alone.
These games did wonders for my masturbation habits. I started rubbing my own clit and sticking a finger inside my vagina. I remember my mom telling me to get my hands out of my pants. I had my first orgasm when I was 6...I thought that I was in Heaven.
These early games have had important consequences on my sexuality now. I am quite the exhibitionist, I'm bisexual, and of course, I masturbate every chance I get.
I would love to talk to anyone about masturbation or used to play doctor when they were little.
