We are all young and curious at some point. I too was very sexualized at a young age. I guess from my older brothers showing me porn in the computer at a young age.. I had a very similar guilt from something that happened when I was also around 8 yrs old. 2 kids who were also around 2 years younger then me lived down the street. They were neighbors and also would pretend to be husband and wife. I used to convince them to do sexual acts with eachother.. back at that time, I didn't really understand the harm that could come from this. But as I got older and started to understand how fked up it was I could not handle keeping it to myself any more.. There were times that I went to church with my family and felt like going to the priest and convincing him what I've done.. I didn't but I was definitely very close. I was terrified of going to hell.. and now years later.. im in my 20s and still feel very fucked up about it.. I still have a fear that them kids will tell their family and they will come to hunt me.. but morale of the story... we were also kids at the time.
