Well it depends. If it is a "good" humiliation it depends on what spanking position I am in. I have always found the diaper position...where you lay on your back and put your legs behind your head, to be a humiliating position. Anything CBT is also humiliating. Really, anywhere where my crotch is completely exposed and on display is humiliating but a kind that I really enjoy.

Bad humiliation would be verbal stuff. I don't really like being insulted constantly and I don't like to be spit on and stuff. I don't mind being called certain things but I HATE being yelled at. Yelling is a huge turn off for me.
