When I was seven years old, I would often wake up in the middle of the night or wake up in the morning, and find my left hand inside my panties. I always thought this was wierd, and wondered why in my sleep, it went there.
One night when I was eight years old, I woke up in the middle of the night to find my hand inside my panties and rubbing my private area really hard. It felt really good, and I wondered how I started doing it in my sleep, and I didn't know what this activity was either. All I knew was that I discovered something really special, and that perhaps I'd been doing it in my sleep for a long time.
I started to masturbate each night before I went to sleep, so that I wouldn't be doing it while I was asleep. I got caught a few times by my mom, but I'd always been asleep when she'd awaken me before and asked me what I was doing (as if she didn't know, lol). I'd quickly get my hand away from there as soon as I woke up. I think the fact that I was fast asleep doing this a lot, made it less embarrassing for me than if I was awake.
