Effectiveness of an independent sexology course for Colombian medical students.

The outcome of an independent sexology course for Colombian medical students was evaluated by means of the Sex Knowledge and Attitude Test (SKAT), stressing the 'material' or 'substantial', rather than statistical, significance of changes after instruction. The results indicate that the course was as effective in producing increases in the students' sexual knowledge as previous non-independent courses, and as effective as them, or more, in modifying positively the students' sexual attitudes. These results are at variance with those of most sex education programmes described so far in the literature, whose effectiveness is in doubt due to the small magnitude of changes after instruction.

Sexual behavior of Colombian high school students.

This paper presents the results of a survey on the sexual behavior of Colombian high school students. It documents significant gender differences in the sexual behavior of Colombian adolescents as compared with the more egalitarian sexual behavior of their American and European counterparts. The study indicates that prostitutes are playing a decreasing role in the sexual lives of Colombian males as a result of a trend toward premarital coital permissiveness among Colombian females. The findings also support previous studies which indicate that there are intrinsic gender differences in the intensity and frequency of sexual desire.

Sexual behavior of unmarried Colombian university students: a follow-up.

Since the mid-1970s, the author has conducted periodic surveys of the sexual behavior of the students of Caldas University, Manizales, Colombia. This study presents the results of the latest follow-up. It documents the accelerated convergence of male and female sexual behavior in a culture which, up to a few years ago, fully adhered to the double standard. The most striking change relates to the increase in the incidence of female premarital coitus, from 38.3% five years earlier to 64.6%, and perhaps 80% among those students who eventually marry. However, the study also shows that prostitution still plays an important role in the sexual lives of male students.

The "G spot" and "female ejaculation": a current appraisal.

In the light of the available evidence, this paper reviews two current controversial issues in the area of female sexuality: the "G spot" and "female ejaculation." It is concluded that evidence in support of the "G spot"--defined as a discrete anatomical structure located on the anterior vaginal wall, which swells upon being tactilely stimulated--is inconclusive, and, in the event of its existence, no evidence has been produced linking it to Skene's glands. However, it seems reasonable to accept that women possess a zone of tactile erotic sensitivity on the anterior vaginal wall, which in many of them may extend to the entire anterior wall and to the posterior vaginal wall. It also seems that some women emit a fluid through the urethra at orgasm, although its true nature and anatomical origin are still unclear.

Vaginal eroticism: a replication study.

Vaginal eroticism was investigated in a group of 27 coitally experienced volunteers by means of systematic digital stimulation of both vaginal walls. Erogenous zones were found in all subjects, mainly located on the upper anterior wall and the lower posterior one. An orgasmic response was elicited by stimulation of these zones in 89% of the subjects. This study supports previous findings regarding vaginal eroticism. It does not support the existence of the discrete anatomical structure called the Grafenberg spot. It supports the contention that there are two distinct types of female orgasm, vaginally evoked and clitorally evoked. It also supports the finding that some women expel a fluid through the urethra at the time of orgasm. In this particular case the fluid was chemically indistinguishable from urine.

Vaginal eroticism and female orgasm: a current appraisal.

In the light of very recent studies, this paper reviews two controversial issues in the area of female sexuality: vaginal eroticism and female orgasm. From the available evidence, it is concluded that most (and probably all) women possess vaginal zones, mainly located on the anterior wall, whose tactile stimulation can lead to orgasm. The apparent contradiction between this finding and the ample evidence indicating that coitus is an inefficient method of eliciting female orgasm might be explained, at least in part, by topographical and mechanical reasons, as well as by differences between male and female orgasm latencies. As to the confusion regarding the types of female orgasm, it may be clarified by applying this concept not to the real phenomenon of orgasm, but only to its manner of elicitation.

Clitoris

Sexual behavior of unmarried Colombian University students: a five-year follow-up.

The results of a 5-year follow-up survey on the sexual behavior of unmarried Colombian University students are reported. On the whole, these findings corroborate the earlier data. Coital incidences of 93.9% among males and 38.3% among females, as well as the important role prostitution still plays in the sexual lives of males, show that the double standard is much in force. However, there are indicators of its erosion, such as male students' decreasing reliance on prostitutes as sources of sexual outlet and the appreciable incidence of female premarital coitus, which could reach 50% among those students that eventually marry.

Vaginal erotic sensitivity.

Vaginal erotic sensitivity was investigated in a group of 48 coitally experienced volunteers by means of systematic digital stimulation of both vaginal walls. It was found that 45 subjects reported erotic sensitivity located in most cases on the upper anterior wall, and of those, 30 (66.7%) either reached orgasm or requested to stop stimulation short of orgasm. This study supports previous findings indicating that the vagina of most women has a zone (or zones) of erotic sensitivity whose appropriate stimulation can lead to orgasm; it does not support, however, the particular location and characteristics of the vaginal erogenous zone described by other authors.

Sexual behavior of Colombian female university students.

The results of a survey of sexual behavior conducted among 113 female students of Caldas University, Manizales, Colombia, are reported. Among other findings, cumulative incidence of masturbation was 68.1% and that of premarital coitus 33.6%. On the other hand, 56.4% of the nonvirgins professed to have had oral-genital contacts and 28.2% of them said that they had experienced anal coitus. While 96.5% of the students admitted contact with pornographic materials and 40.4% had been sexually aroused by these materials, 18% of those subjects who had been exposed to "romantic" (nonsexually explicit) materials professed to have been sexually aroused. As to contraceptive practices, many students never used any contraceptive methods, and 11.4% of the coitally experienced respondents admitted to having had an induced abortion. This study also shows a negative correlation between religiosity and the subjects' sexual behavior. Highly significant sex differences in sexual behavior among Colombian university students are also revealed when this study's findings are compared with data from male medical students.

Brothel prostitution in Columbia.

Peculiarities of Colombian brothel prostitution as well as its similarities to that practiced elsewhere are reported. Data gathered through interviews with a group of brothel residents in Manizales, and by means of participant observations in the brothels of several Colombian cities, indicate that economic factors play an important role in its etiology and maintenance. Incomplete "commercialization" of this prostitution system is described along with the negligible role played by pimps and the freedom Colombian prostitutes have to dispose of their earnings. Misconceptions about prostitutes pointed out by other authors (Pomeroy, 1965; Gebhard, 1969), such as marked infertility, irreligiousness, and homosexuality, are also contested by this study. Pomeroy's and Gebhard's findings of the prostitute's lack of regret about her trade are not confirmed. It is the authors' contention that prostitution shows ample sociocultural variations and that theoretical generalizations regarding it do not apply to different cultural milieus.
