Small penis humiliation or SPH (in Portuguese: "small penis humiliation") is a verbal form of erotic humiliation within BDSM practices where a dominant person usually degrades the penis of a submissive partner. The practice may involve sexual acts or just verbal humiliation itself that can be performed in a public or private setting. Submissive men who like SPH do not necessarily have a small penis. They generally like the idea of being humiliated and having their penis treated as useless, especially involving offenses related to penis size or making fun of the penis in general. Some women have sexual arousal with the power to judge and humiliate a man's penis. For many people, the act of weakening the sense of masculinity imposed by society can be erotic. SPH is often associated with the cuckold when the submissive man is rejected and humiliated on the grounds that he cannot satisfy his partner or that his penis is not big enough to give pleasure to someone. Some people also link SPH with the feminization fetish and, in some cases, even compare the size of the submissive's penis with the size of a clitoris during consensual humiliation, however, this form of degradation is not well accepted by most dominators. because they think that female genitalia should not be used as an offense. Small penis humiliation is often performed over the internet, where the submissive shows a picture of his penis in order to be humiliated. In many cases, there are also BDSM sessions via webcam, where the dominatrix humiliates the submissive through videos, a common practice on some adult entertainment sites.
