When I was about ten years old, I was lying in my sister's bedroom; I guess no one was home and I was lying there with an erection. I started to rub it against a stuffed animal. It felt so good doing that, that I didn't stop, I just kept rubbing and rubbing. I could almost feel something building up in my dick like I was gonna pee or explode or something.
Well, it finally did. I was wearing clothes but I could feel something wet and sticky inside my underpants. When I looked, I noticed a combination of stickiness and blood. It was the only time that there was blood. I was concerned, but since it never happened again, I never mentioned it to anyone. I would have been too embarrassed to do that.
I was wondering, has anyone else had a similar experience?
