need help

i’m struggling. so i’m a nanny and i had an intrusive thought to like do something bad to him so i was very upset crying saying i don’t want to do it but as i was changing him i got closer to it to see if i would actually do it and i got grossed out. now im feel extremely guilty i even got closer.

i did something terrible trying to prove to myself that I can get """arousal""" even without being attracted because i was very nervous about pocd, I thought about several people that i'm not attracted to and then i did it thinking about a loved one and now I can't stop crying, It was very disgusting, I didn't even want to do it because I didn't feel good, but it's because I wanted to prove to myself that, I don't know. I just wanted to relieve the anxiety but it only got worse because I felt horrible doing it. I never want to do it again. im not attracted to this person, nor do I feel anything like that for them, but I feel terrible now, I've never been so scared. i want to apologize to them too. is this compulsion????? what was i doing? why did i do this, i feel horrible but i i want to test myself again, i don't know why (im using a translator, there may be something wrong, please help me)

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.
