Algolagnia
Algolagnia (from the Greek "άλγος" algos meaning pain and "λαγνεία" lagnia meaning lust) is the
paraphilia of deriving
sexual pleasure from physical
pain.
It may have a simply biological basis, as it is proven that pain, just like sensorial pleasures such as sexual contact and sweet foods, causes the release of endorphins, the chemicals that induce pleasure.
If a person's pain threshold is sufficiently high, this may outweigh the normal discomfort, even to the point of addiction.
Note that algolagnia is not the same thing as physical
masochism, since there are fewer
psychological connotations to algolagnia, which may be a simple liking for pain, without any need for domination, submission or humiliation. It may therefore rather take the form of self-infliction of pain.
