The assumption is evidently made that sexual desire and desire problems are the same in both gender groupsa concept that is debatable buy 250 mg ciprofloxacin amex. Although clinically useful buy ciprofloxacin 500mg overnight delivery, these syndromes have not been the subject of empirical research discount ciprofloxacin 750mg with mastercard. Nevertheless generic ciprofloxacin 1000mg free shipping, one can sometimes extract information from survey data that seem to apply to this scheme generic 750mg ciprofloxacin fast delivery. They also described another group of men about half as large in number as sexually apathetic in that they never, at any times in their histories, have given evidence that they were capable of anything except low rates of activity (p. One could conclude from Kinseys observations that not only did these men have a lifelong and generalized disinterest in sexual matters, but also they were quite unusual. Lifelong and Situational The most striking feature that differentiates a situational desire disorder from one that is generalized is the continued presence of sexual desire in some form. The sexual feelings that do exist in the present occur typically when the person is alone and are manifest either in thought and/or action (through mastur- bation), rather than in sexual activity with the patients usual partner. She asked her family doctor to refer both of them because of his disinterest in sex. Alex was initially reluctant to talk with someone else about this issue but eventually acceded to Sharons strongly worded request (and that of the consultant) that they been seen together. When a consultation took place and when they were asked for details of their sexual difculties, she said that the last time that any sexual activity occurred was 1 week ago but before that was 3 months, and before that was 5 months. In talking with them of the history of their premarital sexual relationship, it became apparent that she particularly appreciated the fact that she did not have to fend-off his sexual advances as she had to do with other men, and more often than not, she would take the initiative sexually. The difference in sexual interest became more apparent immediately after their marriage. To her great distress, no sexual activity occurred on their honeymoon and since then, had been only a few times each year. She described regularly comparing herself to women friends who would complain about the opposite, namely that they were not particularly interested themselves and frequently had to resort to subterfuge to control the sexual insistence of their husbands. She initially blamed herself for this state of affairs and wondered whether he found her attractive anymore and if he, in fact, still loved her. She also considered the idea that maybe he was inter- ested in another woman, or that he was gay and interested in a man. She even- tually satised herself that those worries were baseless and concluded that it was he that had some sexual difculty. While nding that sexual offers from other men bolstered her opinion of herself, these were consistently declined because that wasnt what I wanted. When he was seen alone, he explained that the same thing happened on the two occasions when he lived together with women before he married, that is, that his sexual desire for them quickly disappeared. With considerable hesitation he revealed that nowadays, he would masturbate several times each week while looking at pictures of nude women on the internet. He knew that his wife would be angry and might even leave him if she discovered his private sexual interests. Given the fact that the testosterone injections did not prove helpful, he accepted the notion that psychologically oriented care might be fruitful. He started to wonder if his sexual difculties related to his family-of-origin and growing-up years. Acquired and Generalized The major differences between the acquired and generalized form of a sexual desire disorder, and the lifelong and situational form, are twofold: (a) the present status represents a considerable change from the past when the patients sexual desire was not problematic for either him or his partner and (b) sexual desire is presently absent in any form. Case study Bob is a 55-year-old man who had been married for 27 years to Marie (not their real names). He has had diabetes for 5 years and the main treatment was diet, exercise (because he was greatly overweight), and an oral medication. He described erection problems and waning sexual desire over the previous 2 years. He reported thinking little about sexual matters in the present and only occasionally trying to engage in sexual activity with his wifeusually on her initiative. He also reported no inclination to masturbate and added that since he married, he didnt need to, given that sexual activity with his wife was sufcient for his sexual needs. His erections with his wife were 5/10 (on a scale of 010 where 0 meant no erection whatsoever, and 10 was full and stiff. He was not aware of morning erec- tions although would sometimes wake up with some swelling of his penis (about 23/10). The last time he recalled a full erection under any circumstance was about 4 years prior. He did not report ejaculation difculties now or in the past but did say that the intensity of his orgasm had lessened. Bob was all the more distressed because his current sexual status was markedly different than in the past. He had read an article in a newspaper about andropause and thought that this might be the explanation of his difculties. Neither oral medications nor three injections of testo- sterone resulted in any sexual change. When he was seen in consultation by a sex specialist who asked about his knowledge of the connection between diabetes and sexual difculties, he recalled hearing something in a diabetic clinic he had attended but confessed that his knowledge was only fragmentary.
