  • A Two Dimension Approach to Understanding Negative and Positive Affective Reactions to First Coitus
    Sexuality & Culture, 2020
    Co-Authors: Israel M. Schwartz, Edward Coffield
    Abstract:

    To gain a better understanding of the dynamics surrounding the initial coital experience of young women and men, this study examined gender differences in affective reactions to first Coitus through a two dimension approach (i.e., positive and negative affect) using subscales of the First Coital Affective Reaction Scale. The sample population consisted of 266 university students (women n = 163; men n = 103). T tests, χ^2 tests, and regression analyses were used to evaluate the study’s three hypotheses. The findings indicated: (1) a greater percentage of women than men experienced first Coitus at an age younger than they perceived to be culturally acceptable for their gender (i.e., perceived norm-behavior discrepancy-PNBD), (2) among women, a positive relationship was found between PNBD and negative affect, and (3) positive affective reactions to first Coitus were associated with circumstances surrounding the event and not cultural/societal sex norms. A salient finding of this study was that negative and positive affective reactions to initial Coitus can be experienced simultaneously with each dimension of affect responding to different factors. Specifically, negative affect was influenced by a somewhat distant influence of perceived cultural/societal sex norms while positive affect was influenced by the immediate circumstances surrounding the event.

  • Affective reactions of American and Swedish women to their first premarital Coitus: A cross‐cultural comparison
    Journal of Sex Research, 1993
    Co-Authors: Israel M. Schwartz
    Abstract:

    Based on Christensen's (1969) theory of relative consequences, I tested the hypothesis that female college students in the more sexually restrictive American culture would report greater negative affective reactions to their first premarital Coitus than would their counterparts in the more sexually permissive Swedish culture. American (N = 217) and Swedish (N = 186) female undergraduates completed measures of affective reactions to their first premarital Coitus, prior noncoital sexual experience, attitudes toward premarital Coitus, and the circumstances surrounding their coital initiation. As predicted, the American woman expressed significantly more negative affective reactions to initial Coitus. On the positive‐affect items there were no significant differences between the groups. Although Swedish women held significantly more permissive attitudes regarding premarital Coitus, the Americans reported significantly more experience with kissing and fellatio prior to coital initiation. Many situational simil...

  • can the controversy about the putative role of the human female orgasm in sperm transport be settled with our current physiological knowledge of Coitus
    The Journal of Sexual Medicine, 2011
    Co-Authors: Roy J Levin
    Abstract:

    ABSTRACT Introduction Spermatozoal uptake, facilitated by uterine contractions induced by oxytocin at orgasm during Coitus, has been a long term concept. Studies attempting its support, however, have been poorly examined especially in the context of the changes in the female genital tract activated by sexual arousal. Aim To examine experimental support for the concept. Methods Using a variety of search engines, mainly peer reviewed articles and un-reviewed books were examined relating to sperm transport and function in the human female genital tract in the absence and presence of arousal to orgasm. Main Outcome Measures Identifying evidence-based data to support authority-based opinion. Results All the experimental observations of sperm or model substitute's transport have been undertaken in women who were not sexually aroused. They fail to take into account that arousal creates vaginal tenting lifting the cervico-uterine complex into the false pelvis away from the ejaculated semen. This delays sperm uptake and transport making conclusions from these observations invalid in relation to transport during Coitus. Studies injecting oxytocin have not used women in their sexually aroused state and used supraphysiological doses unlikely to be comparable with Coitus and orgasm. The proposal that the transport of extra sperm by oxytocin-induced uterine contractions at orgasm is needed to facilitate fertility ignores possible harm from increased sperm numbers creating polyspermy and sperm enzyme release causing ovum degeneration, leading to decreased fertility. The role of sperm motility in their uptake from the vagina into the cervix as opposed to en bloc transfer through uterine archimyometrial-mediated transport in the absence of orgasm is at present unresolvable because of conflicting studies. Conclusion The bulk of the reported evidence favors the conclusion that the female orgasm, with its concomitant central release of oxytocin, has little or no effective role in the transport of spermatozoa in natural human Coitus. Levin RJ. Can the controversy about the putative role of the human female orgasm in sperm transport be settled with our current physiological knowledge of Coitus?.

  • Satisfactory urethral Coitus in a patient with vaginal stenosis: case report
    International Urogynecology Journal, 2012
    Co-Authors: Mehmet Sakinci, Arif Kokcu, Erdal Malatyalioglu
    Abstract:

    Urethral Coitus is a very rare sexual disorder seen in women either with intact or anomalous vagina such as vaginal agenesis or imperforate hymen. Only about 25 cases have been reported in the literature. We report a case of urethral Coitus in a patient with surgically corrected ambiguous genitalia due to congenital adrenal hyperplasia. The patient had megalourethra and stenotic vaginal introitus. Megalourethra was corrected by plication technique. Correction of megalourethra with this technique has not been reported in literature up to now. To the best of our knowledge, the present case is the 26th of total cases with urethral Coitus reported so far and the first case of urethral Coitus associated with a stenotic vaginal introitus developing due to surgically corrected ambiguous genitalia.
