Study of the orgasm

So far, I have collected 13 self-stimulation orgasms but only 6 orgasms brought about through partner stimulation. The goal is to have an equal number of both. I feel the familiar wash of anxiety about to launch me into the low-level panic typical of a graduate student in her dissertation year.

4 things about female orgasms researchers actually study

Orgasm is one of the most intense pleasures attainable to an organism, yet its underlying mechanisms remain poorly understood. On the basis of existing literatures, this article introduces a novel mechanistic model of sexual stimulation and orgasm. In doing so, it characterizes the neurophenomenology of sexual trance and climax, describes parallels in dynamics between orgasms and seizures, speculates on possible evolutionary origins of sex differences in orgasmic responding, and proposes avenues for future experimentation. Here, a model is introduced wherein sexual stimulation induces entrainment of coupling mechanical and neuronal oscillatory systems, thus creating synchronized functional networks within which multiple positive feedback processes intersect synergistically to contribute to sexual experience.

The duration of the orgasm was obtained using the subject's verbal indication of its start and finish. The estimated duration and the subjective experience of the orgasm self-graded on a 5-point scale were also obtained in a number of subjects. Vaginal blood flow was assessed by the power consumption needed to keep a heated oxygen electrode, held on the vaginal wall by suction, at a constant temperature. The mean measured orgasm duration was
