Can you get worn out on masterbation?

So i’m 15, i’ve been masterbating since i was probably 11 and i’ve always done clitoral stimulation. I’ve never fingered my self. I watch porn or mainly read erotic stuff but lately i can only orgasm MAYBE one time. I just feel like i have a high self drive (i am not losing my vcard soon) but i can’t get myself there. What do you think? Maybe i should take a break or try to finger myself? Get a toy?
