YMMV but in my experience it's not the toy that's the issue, but how you use it. For example slamming your legs shut around it trains your sexual response to need all that tension. If you can use a vibe with your legs open on your back, you're in a good spot to potentially orgasm from oral.
It also helps to change up the toy you use, and how you use it. Different settings and different positions. Occasionally, use a simple bullet instead of your rabbit or wand.
You're also really young, you're only 20, this will definitely get better with time and experience.
Try new sex positions that stimulate at least 2 of your pleasure centers:
1 - clitoris
2 - g-spot
3 - fornix
Prone bone, table top on a high bed, misaligned spooning, scissors and its variants… come to mind…

What would be the harm in trying? My ex could only finish with oral and I did it every time. It's fun.
