is my vagina numb?😂

so i am a virgin but my sex drive is super high and i’ve just been craving sex, but we’re not gonna talk about that.

i started masterbating from a very early age, but now that i’ve become older (im 15) i find it hard for me to cum or even have an orgasm by masterbating. like when i do masterbate i only feel a sensation for about 5 seconds then it’s gone and i don’t cum. what does this mean? and i’ve tried fingering myself and using penetration toys but nothing is helping, kinda feels like nothing. and i’m scared that when i finally have sex i’m not gonna feel anything. any idea what could be the deal?
