Abstract
The researchers set out to obtain self‐reports of individual's orgasm reactions in an attempt to discover whether individuals discriminate between orgasms in qualitative terms using consistent physically identifiable parameters of differentiability such that one can talk about ‘types’ of orgasm. Respondents were asked whether they considered themselves to have a single type of climax or to have several different types, and were asked to describe their physical reactions as fully as they could. By indicating two classes of myotonic responses, one involving body rigidification, the other pelvic movement, respondents indicated two mutually incompatible reactions, each with its own quantitative variability. This suggests the following heuristic research framework: that an increase in orgasmic response leads to an increase in myotonia, but myotonia may be of two types, involuntary nonmovement, i.e. a locking the body during the genital spasms or involuntary body movement, i.e. pelvic‐thrusting and/or folding‐at‐the‐waist.
