I probably was first penetrated when I was about 8
[Woman who as a child was in a commune:] I probably was first penetrated when I was about 8, after some years of playing at it with younger boys. Fellatio may have been practiced even younger, I'm not sure after all these years and it doesn't matter. I began to have little orgasms at about 11, had my first periods at 12 and had a marvellous surprise party and a big fuss made over me as a result. By 14 I had a moderately buxom bust and womanly curves at the hips and was interesting to fellows much older than I.
