I have gooned to bbw, yaoi, futa, loli/shota, toddlercon, bestiality, incest, guro, interracial. How much lower can I go?

Is it normal to not feel guilty for jerking to fucked up things? Years ago if I would give in j would feel very bad arrears for awhile but nowadays it’s just like “eh” and I go on with my day. Do I have brain damage?

Let’s get out of this life
I’m afraid and alone
