I have an electric guitar: Ibanez GRX20Z, and it needs some truss rod adjustment. I asked all other GRX owners what size allen key they use, they say 5mm. My dad has a set of allen keys with all sizes including 5mm. It won't fit in and none of the other allen keys will.

Any ideas?

Its very small but it still doesn't fit in.

Can anyone give me some advice how i can put my dick in?

ibanez truss rod requires a special key, it's sort of like an allen key with a socket on it

No they don't, I've adjusted mine just fine with a normal allen wrench.

OT: I used the 4mm allen wrench that came with my fender, try using a 4mm one
