I can't go back to all natural masterbation 😖

So I've been masterbating for a couple months now and started just with my hand which was great but I bought a small viberator and it's amazing. The problem is I can't go back to just using my fingers which produced a different sensation then my viberator which is awesome too. Can someone tell me what wrong with me and why I can't go back? I like both orgasms I get but i would like the to switch back and forth.
