This survey of sexual practices in the United States has been combed by the media for items of interest to the public: monogamous sex is much more widespread in this country than has been thought; infidelity is less frequent than presumed; vaginal intercourse is the defining experience of heterosexual behavior; watching one's partner undress is stimulating to many people; married couples have more sex than single people (unmarried, cohabiting couples have the most sex of all); the majority of couples experience sex twice a week to several times a month; 2.8% of men identify themselves as homosexual and 1.4% of women do so, but a higher percentage of people consider a same-gender experience to have some appeal; 75% of men always experience orgasm compared with 28.6% of women, but more nearly equal numbers of men and women declare themselves satisfied with their sexual experiences. The book is, in fact, a

Premature and Delayed Ejaculation: Genetic and Environmental Effects in a Population-Based Sample of Finnish Twins

The existence of genetic effects on gender atypical behavior in childhood and sexual orientation in adulthood and the overlap between these effects were studied in a population-based sample of 3,261 Finnish twins aged 33-43 years. The participants completed items on recalled childhood behavior and on same-sex sexual interest and behavior, which were combined into a childhood gender atypical behavior and a sexual orientation variable, respectively. The phenotypic association between the two variables was stronger for men than for women. Quantitative genetic analyses showed that variation in both childhood gender atypical behavior and adult sexual orientation was partly due to genetics, with the rest being explained by nonshared environmental effects. Bivariate analyses suggested that substantial common genetic and modest common nonshared environmental correlations underlie the co-occurrence of the two variables. The results were discussed in light of previous research and possible implications for theories of gender role development and sexual orientation.

Common genetic effects of gender atypical behavior in childhood and sexual orientation in adulthood: a study of Finnish twins.

Associations between number of children, pregnancy, and overall relationship satisfaction were explored in a population-based sample of 2081 women, aged 33-43 years. Multiparous women had less orgasm problems compared to nulliparous women. Nulliparous women had more pain problems and were sexually less satisfied compared to women with children, regardless of the number. Women pregnant with the first child had fewer pain problems compared to a matched nonpregnant control and were sexually more satisfied. Being more satisfied with the overall relationship was related to higher sexual satisfaction and less sexual function problems.

Female Sexual Function and Its Associations with Number of Children, Pregnancy, and Relationship Satisfaction

The association between disordered eating and gender identity was examined in a sample of 20 (11 female-to-male, 9 male-to-female) transgender Finnish adults, aged 21-62 years. Using semi-structured interviews, participants' own understanding of the underlying causes of their disordered eating was analyzed, as well as the effect of gender reassignment on eating behaviors and cognitions. A majority of the participants reported current or past disordered eating. Participants most frequently described strive for thinness as an attempt to suppress features of one's biological gender, or accentuate features of one's desired gender. Gender reassignment was primarily perceived as alleviating symptoms of disordered eating.

Disordered eating and gender identity disorder: a qualitative study.

This study explores the relation between the level of current symptoms of depression and anxiety and recalled childhood gender atypical behavior (GAB), and quality of relationships with parents among men and women who reported same-sex sexual attraction or engaged in same-sex sexual behavior and men and women who did not. Matched pairs, 79 men (n = 158) and 148 women (n = 296), with equal levels of GAB were created of Finnish participants with either same-sex sexual attraction or behavior and participants without. The measures used were retrospective questionnaires. Ratings of maternal and paternal over-control and coldness differed as a function of same-sex sexual attraction or behavior. Childhood GAB was correlated with negative ratings of parental relationships. Both same-sex sexual attraction or behavior and a history of childhood GAB affected the reported levels of current depression and anxiety. Only gender typical participants with no same-sex sexual attraction or behavior reported significantly lo...
