Expanded Sexual Response
in the Human Female: 

The Mechanisms of Expanded Orgasms in Women                               


 H. Ümit Sayin and Asiye Kocatürk


 In DSM-V (2013), a new sexual disorder will be defined as “Hypersexual Disorder” in the human female, described by Martin P. Kafka and APA , according a new scale called HDSI (Hypersexual Disorder Screening Inventory). However, lately there have been very fierce debates about the validity of HDSI in the academic circles . Recent publications on human female sexuality point out that sexual response can be enhanced and expanded in the human female (Taylor, 2002 ; Rhodes and Brauers, 1991 ; Komisaruk, Beyer-Flores, Whipple, 2006 ; Sayin 2010, 2011, 2012 ). This phenomenon has been coined as “Expanded Sexual Response” (ESR) in the human female. In the internet surveys of Winters  and ours , 21.5 to 29 % of women, some of which may have developed ESR, may be misdiagnosed as Hypersexual Disorder, after the validation of HDSI in DSM-V. Our various surveys and internet communications, which are still continuing, have revealed that, ESR phenomenon exists in the human female.

Definition of ESR: Being able to attain long lasting and/or prolonged and/or multiple  and/or sustained orgasms  and/or status orgasmus that lasted longer  and  more intense than the classical orgasm patterns defined in the literature .

We have investigated cases of more than 50 women who claimed to have ESR, and a control group of women who do not have ESR (NESR). The analyzed data of 35 ESR women is presented here, and the study is still continuing, some figures and percentages may change. It is concluded that some aspects of the sexual response of women with ESR were different than the women without ESR (none-ESR, NESR): 1) The ESR women experienced vaginal, clitoral and blended orgasms, as described by Ladas, Whipple and Perry . 2) The ESR women experienced multiple orgasms in most of their sexual activities. 3) The ESR women were able to attain long lasting and/or prolonged and/or multiple and/or sustained orgasms that lasted longer than the classical single orgasm and/multiple orgasm patterns defined in the literature. 4) The ESR women claimed to have strong pelvic floor muscles (PFM) compared to NESR women. 5) The libido of ESR women was very high compared to NESR women. 6) ESR women described a phenomenon called G-Spot orgasms. 7) ESR women described sensitive erogenous zones (DVZ: Deep Vaginal Erogenous Zones) in their genitalia other than glans clitoris.  8) ESR women masturbated very frequently. 9) ESR women had erotic fantasies more frequently than the NESR women. 10) ESR women admitted to have a form of altered states of consciousness during some of their prolonged orgasms .

Conclusion: We have concluded that the extents and limits of female sexual response, including ESR phenomenon in women, should be investigated thoroughly before deriving any conclusions that may lead to ambiguous pathological diagnosis patterns by certain classifications such as DSM-V.
