How can i get myself to orgasm?

I’m almost 18 & i’ve been masturbating since i was in 6th grade. I have never been able to make myself orgasm & it’s really frustrating. My boyfriend has even tried fingering me to see if he could & i still couldn’t. I’ve wanted to purchase a vibrator or something just to see if that could possibly work cause i’m to the point where i’m tired of not being able to. It’s literally been my goal to make myself orgasm before i even lose my virginity & it looks like i’m not gonna be doing either anytime soon 🙄
