What are the underlying processes occurring during an orgasm that are the biological causes of the pleasurable sensation we associate with it? Is the sensation of orgasm a function of the nervous system, or is it something neurochemical in the brain, or both, or neither? Is the reason that certain masturbatory and/or sexual acts feel good because of nerve concentration in the erogenous areas, or is it something different or more in nature? [more inside]
