Has anyone experienced this before?

I went to a fast food place where my boyfriend works and I was actually excited to see him because I missed him, but while I was in the car I started overthinking because I got that sensation down there again that I started labeling as sexual. I imagined seeing him and kept thinking about the feeling, but once we got there it went away. Then I saw my boyfriend and we smiled at each other and that certain feeling I associate with him came back, and I felt happy. I kept looking over at him, but then I noticed I wasn’t feeling the excitement I usually expect to feel, so I started checking myself and wondering if I was actually happy or if I was feeling the right thing. I smiled really big when he looked at me, but afterward I couldn’t remember exactly what I felt and that made me anxious. On the way to a grocery store I suddenly thought, “I think I do like girls,” and I felt like I wanted to cry, and then I got that sensation down there again and didn’t know why. I didn’t test myself with girls, but I still felt anxious in my chest. I eventually felt okay again. I also got hand wipes and thought I should get two for me and my boyfriend , and I felt anxious for a moment but then felt okay. Later I started thinking about how I want to buy my boyfriend a shirt, and I said I wanted to get him one but didn’t feel anything noticeable, which confused me. I started wondering why I can want to do something for him but not feel the emotion in my body. I also looked back at pictures of him and remembered moments from when we were together, including hearing him say “baby,” and that brought back the certain feeling again. It felt like I was visiting a dream or going back into a familiar emotional state from when we were together, where I felt very clingy and affectionate toward him, and I felt emotional enough that I wanted to cry. Then I started worrying that calling him by his name instead of “my boyfriend” meant something or meant I was going to break up with him, which made me anxious. Later I was looking at Awkwafina posts and got another certain feeling with a thought like “you like girls” and “figure yourself out,” followed by a rush of adrenaline and anxiety. My brain then made it feel like the rush was proof of something when I felt this empty bland feeling , and I started wondering if I had figured myself out. After that I thought about my boyfriend again and got worried about what that meant. Then I saw another girl doing a pretty pose and got a different certain feeling that felt more like a rush of adrenaline , followed by light anxiety. I wondered if I was accepting something, and then I saw a loveydovey video that I wanted to send to Erick while the anxious feeling was still there. At one point I tried testing the feeling with a girl and got another certain feeling with high anxiety, then it went away and I checked to see if it was still there. Now I feel like the adrenaline came back, but instead of feeling it mainly in my heart, I can feel anxiety more throughout the outside of my body. Overall, I’m really confused because the sensations keep changing and sometimes feel new, and my brain keeps making them feel like they are proving something about my feelings even though I don’t know what they actually mean.
