The first 'tingly' feelings I felt were when I was still in diapers. Whenever I had this diaper change my mom would always put some of that powder on my private area. Do you know what I'm talking about? Anyways, I had no idea I could create that feeling on my own, but when my mom did this, I looked forward to it each time. It was only touched for a split second, maybe half a second when she did this, but all I remember is that it felt nice.
Of course once I was potty trained, I didn't need my mom to do this for me anymore. I missed that feeling that it gave me though, and I always remembered back to it and wished to have it again.
One day several years later, probably seven or eight years old, when I was having a bath, I was looking at my vulva and remembering the feeling I used to get when my mom placed powder on it when I was a baby. I wondered, 'if I touch it myself in the same sort of way, will I feel anything?' So I lay down in the bathtub, and spread my legs slightly apart. I took one of my hands and kind of slapped my vulva. It felt so good! I kept doing it continuously for a few minutes, and wow I was so excited.
Years passed, and I continued doing this activity whenever I had a bath. I drew no connection that I could do this anywhere, I thought I had to be naked and in the bathroom to do it.
Anyways, one time when I was having a bath, probably by now twelve years old or so, I wondered what exactly was in between my legs. I stood up and took a closer look in the mirror, and also slightly caressed and touched and rubbed my vulva, vagina, and clitoris areas with my fingers and my hands. I didn't know the names of all of these parts at the time; I was just discovering what they look like, and feel like. But with this discovering, I discovered a more convenient way to masturbate, simply by rubbing. I began to rub in my bedroom at night time, or when I wake up, or simply when I was bored.
I look back now, and just think that it's really funny how my mom really was the one that showed me this secret. She never realized for this to happen or come of it, but apparently that dabbing on of powder when I was a baby was enough to cause me to discover masturbation when I was older.
