I wuz 11 yrs. old, sixth grade. For some wierd reason, (don't remember) I had put Burts Beeswax lip balm on the thing and I just started rubbin' it...
Oddly enought, I had first seen porno about a year before and it still took me that long to figure it out.
Places i did it: In bed, On the floor, computer chair, la-z-boy, floor, hotel, sofa upstairs+downstairs, Aunt's house, and in a bunk on a school trip.
