Definition - What does Penis Humiliation mean?
Penis humiliation or small penis humiliation (SPH) is a male fetish where men get turned on when their partners belittle the size of their penis. This is regardless of the man's actual penis size. He can have an adequately sized penis and still crave penis humiliation. In fact, a good number of men who claim to experience SPH have average to large-sized penises.
Kinkly explains Penis Humiliation
There are several theories about the roots of the small penis humiliation. Some say that it is a social phenomenon that results from interactions where size comparison is made possible. This includes male friendships and locker room interactions. Others say that it is a body dysmorphic disorder stemming from unrealistic expectations. One of the culprits here is excessive porn watching.
