What is wrong with me

I feel like there’s something wrong with me because I am 17 years old and I’ve never even been horny before and I don’t think that’s normal. I’ve never really masturbated cause Ive never really felt like doing it. I’ve tried it once or twice for a little bit but I felt nothing and tbh I don’t even know how to. I think I’m like this because I am so insecure about my body and I have a fear of anyone looking at it or even touching me. I also have past experience that traumatized me and even thoughts about doing anything makes me feel violated and idk why. I know I’m not asexual or demisexual but I feel like there’s something wrong with me. Is there something wrong with me??
