Thought Action Fusion??

I have been struggling today, most likely due to lack of sleep. I had a thought that I would consider intrusive, but what really unsettled me was that I felt like I liked it, **not just in the sense that I lacked anxiety over it, but that I genuinely felt like I wanted it.** It left me feeling really confused. It happened during intimacy, which makes it even more unsettling. The thought was incestuous, I found myself imagining and comparing the moment with my boyfriend to my father :/, and what really alarms me is that I felt like I wanted it there, both mentally and physically. I was having a really nice time, so maybe the physical sensations got mixed in somehow, but it still worries me. I did my best not to ruminate in the moment and avoided checking. I tried to move on, but the feeling of genuinely liking the thought was so clear that it is hard to shake off. Has anyone else experienced something similar? This is one of the first times it has ever happened to this extent.

I already made a post about this but I have theory over what might’ve happened because I can’t really stop freaking out about how much like me it felt. My boyfriend told me his cousin grabbed his other cousin’s girlfriend’s boob while drunk. Later, I started imagining it happening to me, with my boyfriend getting defensive (I love drama-filled moments in stories). Then, I thought, “Why couldn’t it have been me?” and got scared. I know I like attention, and I’m worried that’s why it felt so real. I almost felt excited. I’m wondering if it was just an intrusive thought or if my brain was mixing up the daydreaming feeling with that. Later that night, I started thinking about how I could position myself to make it more likely to happen, and I immediately felt horror. I’m into things like CNC, and I’m wondering if my brain got confused, mixing the daydreaming excitement with that preference, which is why it felt so real? I don’t know. I’m feeling scared because it genuinely felt like me both times. Has anyone else experienced this kind of brain confusion? Is that even possible?

Without trying to seek reassurance, I’m wondering if anyone has insight on identifying an intrusive thought vs reality. Something that’s always really helped ground me in moments of false memory ocd is clearly remembering the exact moment the thought arose and how it started as “what if I cheated and don’t remember.” Then the images come and are extremely distressing, but I’ve always found some comfort in coming back to that moment of “this started as what if.” It feels like my brain is almost getting more creative with the thoughts now, and I’ve been having probably the worst anxiety of my life the past couple months after another intrusive thought entered my mind. I woke up after a night drinking and thought to myself “did you kiss your friend and don’t remember?” (Didn’t happen, undeniably proved). The rest of the day I stayed anxious about other things I could have done and poured over all my memories of the night. Then the next day I finally had found some peace based on all the evidence from my friends who were with me that nothing bad happened. I then thought “what about when you went to the bathroom,” which I hadn’t really been thinking about before, and then my mind immediately started flashing with images of me performing sex acts in the bathroom with some person who has no name, face, details, or anything I remember about interacting with them. I think I’m just concerned that this was a moment of genuine memory recall since I hadn’t been thinking about the bathroom before, and it was more of a sudden flash of images and “did you do that” vs “what if you did that.” I’m wondering how others are able to identify that something is an intrusive thought vs reality.
