Someone please help me 😢

Today I was scrolling through Instagram reels and saw a video that briefly looked sexual to me, even though it wasn’t. I see a man and a women you know ( sorry I don’t want to give to much) and I felt a sensation that was familiar and it when me and my boyfriend were really close and intimate. While that imagine was playing while I was like also watching reels the guy and girl kept automatically switching to a girl and girl. The switch felt intrusive and unwanted, and when it happened my heart dropped and I became scared and upset. I noticed that the images felt very vivid and immersive, almost like I was “there,” and I still felt that sensation which made me worry that they meant something about me. It played in the back of my mind or when I’m like read comments , or telling myself that “I don’t like girls , I like boys “ repeatedly, and while it intrusive thought I can feel that sensation that felt familiar sensation and it makes me feel so sad and mad because was that sensation for image? And sometimes I wonder did I see the girl and guy?then i get worried if I was lying to myself and making excuses . I started questioning whether the thoughts felt like me and whether they meant I secretly wanted them, even though I didn’t want the switch to happen and it upset me when it did. Recently I’ve also noticed that I sometimes feel “normal” or emotionally flat during these thoughts instead of panicking like I used to. This confuses me because I worry that feeling normal means I secretly like the thoughts or am accepting them. I also notice that intrusive images can automatically insert girls into situations where I normally imagine my boyfriend, and I become afraid that this means my true feelings are changing. I feel confused because the thoughts and images can feel real, vivid, and personal, and sometimes my body reacts or I become hyperaware of sensations. I often question whether these reactions mean something, and I find myself worrying that I’m discovering something hidden about myself.
