Haven't Been Able to Orgasm

Hey there, so, I have a question regarding masturbating.

I'm a virgin, I've experimented in the past with my fingers, but I can never...get myself to the point of orgasming. Like, yes, there's points where it feels good and I get turned on, but it doesn't effect me otherwise. I can't purchase toys because even though I'm an adult, my parents are strict and have no sense of privacy.

I get really frustrated that I can't orgasm or haven't been able to and I've honestly kinda given up. Any tips or suggestions?
