YOU SAID:
i like to finger my crack
INTO JAPANESE
私は私の亀裂を指にしたい
BACK INTO ENGLISH
I want to finger my crack
INTO JAPANESE
私は私の亀裂を指したい
BACK INTO ENGLISH
I want to point to my crack
INTO JAPANESE
私は自分の亀裂を指したい
BACK INTO ENGLISH
I want to point to my crack
That didn't even make that much sense in English.
