Earlier today I randomly remembered a couple times from when I was probably about 14 or 15 and I looked up incest porn. i remember watching some videos that looked kind of amateurish and grainy/not well shot and it hit me that maybe they were videos of real incest. i remember that the search terms i used were something like 'real brother real sister,' but i'm not sure if i had used those search terms to distinguish between fake stepsibling porn and fake sibling porn or if i used those search terms to find real incest. all of a sudden these thoughts triggered a bunch of memories from around that time, including me fantasizing about my younger sister, who was about two years younger at the time. i'm partially afraid that i technically molested her or something because of this one time when i believe i (ughhh i feel so awful) lightly punched her breasts, maybe because i was horny or out of sexual curiosity or something like that. though i have been diagnosed with OCD concerning these sorts of things, i'm terrified and really overwhelmed by all these thoughts. i feel really dark and like i'm a depraved criminal who's done terrible, terrible things. i'm afraid that maybe i really was interested in acting out those fantasies, and that i did want to do those things in reality. i'm totally horrified and i'm afraid that if my friends knew about this they would think i was disgusting. i'm just so scared because, this whole time with my CBT specialist, we've been saying that it was just a fantasy, and that fantasies are harmless; part of me thinks that this means i wanted to do it in real life, and it wasn't a fantasy but a truly sick desire that i had. the idea that maybe i would have hurt someone or hurt my sister or something, but i was just holding myself back makes me want to cry. the incest porn thing is also so scary because i feel that it's possible i was looking for real incest porn, which makes me feel so immoral and dirty and horrible. though i was a kid, i was still in high school i think - i feel pretty sure no normal, well-adjusted high school kid would ever do that. maybe i was just a kid and was trying to figure things out, and was confused or something? i can't stop having all these terrible thoughts of how dark and evil i feel i am. i'm convinced that my moral life is essentially over, and that there's no way i can ever be a good person because of this. i don't know of anyone who's done anything like this, so as far as i know i'm really, really strange and messed up. please help - am i a sick disgusting perverted person who's done terrible things, or am i just someone obsessing over relatively normal childhood mistakes?
thank you so much for listening.
