Hey guys I'm 17 years old I had experience with OCD I looked trans pornography and femboy stuff I'm straight I didn't jerk off to it I was really only looking at it in the past I have but for some reason I just felt like looking at it and when I did I did experience arousal not only that while I had a boner I simultaneously was thinking of memories and bad actions I had in 4th grade with another boy I myself not a homosexual I was a kid I did something with another boy I regret it I had that thought in my head lingering there in my head but I noticed pre ejaculation and now I feel anxiety because now it feels like I was intrigued by the thought it feels like it is it was probably to the video visual stimulus but it's hard I didn't jerk off to it at all I was really just looking idk what to do it feels like I did experience it to the video but also my thoughts say to the thought idk what to do can someone shed light on this

help. it all happened too very fast. i was having a random b*ner, and i wanted to stop it by forcing an er*ction so it would go down afterwards, i had also seen a yt short of cyberpunk 2077 phantom liberty, in which a beautiful redheaded character appears, and i had random thought abt how maybe she wouldn't be truly that pretty and it was just make up. i imagined a scenario in which i had an okay looking girlfriend but that would look very hot with make up on, and i thought that was the perfect scenario to release the b*ner by momentarily forcing an erection and as i did that i remembered a highschool crush i had of a girl older than me that i found very beautiful and i distinctly remember being excited to see her with make up on, and this memory associated immediately. it went like this -> imagine girlfriend that is beautiful with make up on as i prepare to have an er*ction -> this reminds me just like that time in highschool -> the positive memory of my crush appears as i force an er*ction to happen at the same time without thinking too much (this all happens in a span of a millisec) i don't know how but my brain didn't register that memory as a threat, i had forgotten the context, it didn't even cross my mind that it happened years ago in highschool, i just had this memory. now im worried that i committed a horrible disgusting act. the erection wasn't caused by the memory of the crush, i planned it to happen with a safe image and that image of the crush appeared as i remembered and it didn't register it as a threat and this just happened; because i don't believe i was aroused by the memory, i was just remember that she was pretty. i don't know if it was just coincidence. it wasn't intentional, but now im disgusted at myself. there are 3 possibilities: 1. i already had made the conscious decision to force an erection from the scenario before and as the memory appeared, as it all happened in a millisecond, i didn't have enough time to process it with its due context and i didnt perceive that memory as triggering or something inappropriate and for my brain it was okay to be in the background while the er*ction happened. 2. it happened in one second, the conscious decision was already made from the scenario before so the er*ction randomly happened during the remembrance 3. worst case: in the moment of the er*ction as i remembered the crush i put myself in those shoes of the young me and as the memory happened very fast i forgot the context and the distance of the period frame in which had happened (long ago) and since i remembered her being older than me i still perceived in that fragment of the memory that way, and since i was in the memory itself i found her attractive normally, indistinguishably and separated from the present time, and for that split second i perceived her normally as if i was attracted to a girl in my present time, it literally felt a "normal" perception of a girl i liked and i didn't realise it wasn't the case; and my mind since it lacked the necessary context it allowed it to be non dangerous and not wrong to force an erection, and i realised it was a mistake only after it happened hence the panic... so it all happened before processing the context of the time in which had happen that would result as inappropriate. im afraid that the 3. is what happened and that it is unacceptable.
