SPH is an acronym for Small Penis Humiliation. It is a fetish that involves making fun of men with small penises and humiliating them. Guys involved with SPH typically seek it out after years of coming to grips with reality. That reality being their total lack of dick. After realizing they can never sexually satisfy is when tiny dick humiliation becomes the perfect alternative. In rare occasions even hung guys find themselves craving this fetish, so it is not only for the micro-dicks.
