I'm failing at masturbating 😩 HELP!!

I recently moved away from my boyfriend of 3 1/2 year due to school (college) and I hardly get to see him. I'm finding myself becoming more and more open to explore my sexuality lately and I also find myself really horny a lot more than I used too. I've tried masturbating many times and I never seem to be able to orgasm or find get full satisfaction out of it. Any advice would be very appreciated! I just want to be able to flick my own bean when I'm apart from him.
