Intravaginal ejaculation disorder is a peculiar Japanese case, but is very similar to "traumatic masturbatory syndrome," which is also mainly caused by intense masturbation. Diagnosis
Diagnosis and management of DE warrant one of the most comprehensive medical evaluation in sexual health assessment that includes a full medical and sexual history performed along with a detailed physical examination. Understanding the quality of the sexual response cycle (desire, arousal, ejaculation, orgasm, and refractory period); details of the ejaculatory response, sensation, frequency, and sexual activity/techniques; cultural context and history of the disorder; partners assessment of the disorder and if the partner has any sexual dysfunction themselves; and the overall satisfaction of the sexual relationship are all important to garner during history-taking.Relatively normal latency to orgasm with self masturbation as compared to insertive or intravaginal ejaculation latency time reasonably rules out most of the organic causes of DEs. Treatment
Primary, lifelong DEs are poorly understood and hence less well studied. Organic causes in the acquired DEs should be addresses promptly. Retraining masturbatory practices and re-calibrating the mismatch of sexual fantasies with arousal are essential when these are contributing to DE. Techniques geared towards reduction of anxiety are important skills that can help overcome performance anxiety, as this can often interrupt the natural erectile function through orgasmic progression. Sex therapy
Therapy usually involves homework assignments and exercises intended to help a man get used to having orgasms through insertional intercourse, vaginal, anal, or oral, that is through the way to which he is not accustomed.
