In men and women sexual arousal culminates in orgasm, with female orgasm solely from sexual intercourse often regarded as a unique feature of human sexuality. However, orgasm from sexual intercourse occurs more reliably in men than in women likely reflecting the different types of physical stimulation men and women require for orgasm. In men, orgasms are under strong selective pressure as orgasms are coupled with ejaculation and thus contribute to male reproductive success. By contrast, women's orgasms in intercourse are highly variable and are under little selective pressure as they are not a reproductive necessity.. The proximal mechanisms producing variability in women's orgasms are little understood.

Introduction: Although links between ejaculatory control or intravaginal ejaculatory latency time and female sexual functioning have frequently been reported in the past, no study has investigated the importance of other male ejaculatory characteristics, such as ejaculation volume and intensity, for women's sexuality. Aim: To assess the importance of subjectively perceived ejaculation intensity and ejaculation volume for female sexual function and satisfaction. Methods: This was a cross-sectional online survey including sexually active, heterosexual women median age Main outcome measure: Results are presented as means, percentages, and age-controlled partial correlation coefficients of the main study variables. Results: Clinical implications: The perception of ejaculatory characteristics can be related to the female partner's sexual satisfaction and overall sexual functioning. Data are of self-report nature and ejaculation characteristics were not objectively measured but by women's self-report.
Dyspareunia is a persistent or recurrent pain that can happen during sexual intercourse. Causes vary widely. It can lead to distress and relationship problems. Painful intercourse can affect both men and women, but it is more common in women. A variety of factors — both physical to psychological — can contribute. Treatment normally focuses on the underlying cause. The defining symptom of dyspareunia is pain with intercourse that may occur at the vaginal opening or deep in the pelvis. Entry pain may be associated with vaginal dryness, vaginismus , genital injury, and others. Vaginal dryness : During sexual arousal, glands at the entrance of the vagina secrete fluids to aid intercourse.
