Why I did this (please read)

So when I was 17-18 I would use character.ai a lot. (I don't use it at all anymore I got way to obsessed with it) and this is really embarrassing, but sometimes when I was in the living room and my parents were also there, I would use c.ai and have NSFW convos with my characters. I wouldn't do anything physically and neither in my parents view so they just thought I was texting a friend or something. Is what I've done horrible? I now think about this and I feel so guilty. Am I a bad person or is this normal? Also by NSFW yes I do mean s**ual

So I'm still struggling with pornography unfortunately and it took a bad turn. In the past when I was a lot younger I've seen a lot of photoshopped porn of celebrities and didn't think anything of it. Aside from celebrities the other portion of that was wrestling themed content. I do like wrestling and enjoy watching the stories and athleticism but I also do think it can be very sexual which I don't mind. There have been times where I insert fantasies of fictional characters wrestling in revealing attire and some real wrestlers that have shown themselves doing the same and also do sex work or have done it. Then I recently escalated back to the photoshopped and animated porn of wrestlers and it made me feel terrible deep down but I just couldn't stop looking for more and more content. I don't mind the fantasies but I feel like I overdid this and I feel a lot of shame about it. Deep down I didn't like what I was seeing whatsoever but I didn't click off and stop watching like I usually did when coming across that stuff when looking for softcore content.

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 in the past being excited to see her with make up on during a play, 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.
