Mine was sitting on the side of the bath when I was 9 years old. I had just started growing pubes around my cock and became suddenly intrigued by what it meant for my body. I looked up puberty and sex in an encyclopaedia and read about how ejaculation occured. I wanted to give it a go, so I stroked my cock for about 5 five minutes and shot a load all over the floor. It felt so amazing I fell back into the bath, but I was instantly concerned about making a mess on the floor!
