What am I doing wrong?

So I mastbate often and as good as it feels, I never feel like I had an orgism. Because if I had I would know right? And I've tried masterbating in other ways but they sorta hurt or just feel weird and I get no pleasure from it. Rubbing my clit just hurts and the shower head does nothing for me. Also I'm 17 so I can't buy a vibrator yet and my mom will see if I order one online. What should I try? Is there something wrong with me?
