A psychology professor here reviews the behavioral, biochemical, and anatomic evidence for the reality of the G-spot. He finds the widespread acceptance of the reality of the G-spot "goes well beyond the available evidence." He calls the G-spot "a sort of gynecologic UFO: much searched for, much discussed, but unverified by objective means." Many women mistakenly think that they can't get pregnant if you have your period. This is false. In fact, a woman can conceivable get pregnant anytime she has heterosexual intercourse. Viagra researchers have been frustrated trying to figure out why Viagra may have an effect in some women but not most. One circulating myth is that most women can feel themselves ovulate. Sexual dysfunctions should be assessed objectively and managed according to the cause. Sexual desire changes over the course of our lives, and occasional loss of desire in either sex is not uncommon. Some women’s symptoms are so severe that they avoid any sexual contact; others may have satisfying sexual experiences through extensive foreplay leading to orgasm without penetration. Premature ejaculation is a condition in men characterized by persistent or recurrent ejaculation with minimal sexual stimulation before, on, or shortly after penetration and before the person wishes it. The treatment of premature ejaculation, using the "pause" and "squeeze" procedures developed by Semans and by Masters and Johnson, has been found to be highly effective. In the stop-start or pause procedure, the penis is manually stimulated until the man is fairly highly aroused. This squeeze seems to further reduce arousal. After a few weeks of this training, the necessity of pausing diminishes, with the man able to experience several minutes of continuous penile stimulation without ejaculating. However, during high arousal, any additional stimulation of the scrotum and perineum may trigger an ejaculation and thus may make the pause and squeeze procedure ineffectual.
