What could all of this mean?

Okay. So I have this thing. I wouldnt call it a problem, but I wanna know what it means. Dont judge me. I have a weird thing with bellies. For one thing, when I go in the shower, I'll lay on my back and palpate my stomach like a doctor. I watch abdominal exams on youtube too. And when I go to the doctor, I get butterflies when the doctor feels my tummy. Why does it make me feel this way?? I just want to know. Is it a bad thing?? Is it normal? What the hell is it?
