WOW! I just discovered this last week and it's AMAZING! I was just laying in bed one night last week and I couldn't sleep so I was kind of exploring myself without really thinking about anything. I was really curious about 'down there' so I started to move my hand around inside of my panties to feel what it was like.
Suddenly, I got the idea to put some fingers in my vagina, so I did. I started to notice a funny sensation, which got me even more curious. I got into this sort of rhythm where I was moving my fingers in and out, and it started to feel better and better. I was breathing hard making noises now, too. I started to notice dampness, which freaked me out a little, but the feeling was so good that I couldn't stop now.
I kept moving my fingers out, absorbing the warm feeling of my vagina. Suddenly, my entire body tensed up and I let out an ivoluntary 'ohhhhhhhhhhhhh' as I had what I have learned is an orgasm. It was the most amazing feeling ever!! I'm so glad I discovered masturbation and this site, and now I masturbate several times a day.
