Toddler Orgasm?

Previously I submitted a story about masturbating with my teen age neighbors but think my orgasms started much earlier. I remember when I was not very old- maybe 8 or 9 I would wake up having to pee. I didn't like getting up so I found that if I rocked myself back and forth on my stomach I would experience a "funny feeling" after which I would not have that feeling I had to pee for a while. Years later I realized I was having an orgasm. My mother told me that while I was a toddler I would often rock myself in the crib. Have to wonder if I learned very early how to pleasure myself.
