The initiation of sexual intercourse is an important topic in the study and prediction of fertility. In their theoretical analysis of fertility and its determinants, Davis and Blake argued that socioeconomic and other factors affect fertility only through its proximate determinants, that is, through exposure to sexual intercourse, exposure to conception, given intercourse, and gestation and successful parturition, given conception. Since under all but exceptional circumstances, conception does not occur without it, sexual intercourse is the first of these proximate factors to be examined.
In the past, fertility was studied primarily within marriage. This was not only due to the difficulty of obtaining information on sexual behavior, but also to the assumption that intercourse takes place primarily within marriage. However, recently the study of sexual intercourse itself has taken on more importance. This is, first, because of the increased separation of sexual activity from marriage.
A substantial amount of sexual activity and, thus, exposure to the risk of pregnancy occurs outside Woman seeking real sex Mott marriage relationship. As a result, an increasing proportion of childbearing occurs outside of marriage—12 percent of white and 57 percent of black children were born to an unmarried mother in NCHS, Although some teens are married, the majority are not.
The proportion of out-of-wedlock childbearing is even higher among teenagers. Thirty-six percent of births to white teens 15—19 and 87 percent of the births to black teens 15—19 occurred outside of marriage in the United States in NCHS, Another important factor is the increase in cohabitation Spanier, ; Blanc, Although the of cohabiting couples with children in the United States is relatively small about 30 percentit increased between and Spanier, Thus not only is the study of factors affecting the initiation of sexual activity among unmarried as well as married women important today, but it has become critical to any prediction of future fertility.
A second important reason for studying the initiation of sexual intercourse is that, above and beyond its impact on fertility, too early sexual activity in or outside of marriage may not be desirable for the youth involved.
This is an important issue. It is generally based on judgements about maturity and physical development that do not progress at the same speed or age for all people. The definition and the consequences sexual activity may have for an adolescent also vary across groups in the society which hold different views on what behavior is appropriate. This chapter focuses on the initiation of sexual intercourse among teenagers. Because of potential differential interest in teens at different ages, ages are divided, where possible, into the three age groups most commonly used in the data: less than 15, 15 to 17, and 18 to Unfortunately little information is available for the under 15 age group, but data will be presented when available.
This paper also focuses on the initiation of sexual intercourse rather than a variety of other sexual activities, primarily because the major interest is in behavior that involves pregnancy risk. However, an additional reason is that the traditional ordered scale of sexual activities which is often used—holding hands, kissing, necking, petting above the waist, petting below the waist, intercourse—does not appear to apply to blacks. The outline of this chapter is the following: The incidence of sexual intercourse among teenagers is first described.
Second, a model of the process of initiation of sexual intercourse is discussed. Third, research bearing on each of the aspects of the model is discussed, following the same logical outline.
In particular, the empirical evidence on the linkages between background factors and sexual intercourse is presented, followed by evidence on the intervening linkages between background and intercourse. The chapter focus is on the research that sheds some light on the process whereby background factors affect sexual activity, that is, on explaining sexual activity.
The reader should continue to refer the model, as the outline follows it closely. According to a nationally representative sample of women in43 percent of never married women 15 to 19 said they had had sexual intercourse Pratt et al. The proportion of all never married teens who report being sexually experienced rises from a low of 18 percent for 15 year olds to 66 percent for 19 year olds.
Blacks are more likely to report sexual experience than whites. These percentages are shown in Table 1. Experience rises almost linearly with age. National figures for on the sexual experience of teen men show that by age 18 two-thirds have experienced intercourse Table 1. Using data to compare rates of intercourse among men and women Table 1.
Unfortunately, only one national data set, the NLS provides data on the sexual activity of teens under age 15 Table 1. Most data we have come from a variety of small area studies; as a consequence the samples vary considerably from study to study. Table 1.
The estimates for young white male and female teens and for black females are consistently lower than estimates for older teens, as one would expect. The estimates for black males, in contrast, are very high, in some cases higher than those of older teens, which suggests low data reliability or unusual samples e.
Of course, having had intercourse once does not necessarily mean the youth has intercourse frequently or regularly. However, it appears that, lacking data on frequency of sexual activity, a measure of ever having had intercourse is a relatively good proxy. In only 5 percent of teenagers 15—19 who ever had intercourse said they had it only once. Almost half of white teens and three in ten black teens said that they had second intercourse within one month after the first. Two-thirds of both races had second intercourse within three months of first intercourse. However, having ever had sex doesn't mean that a young woman is currently sexually active, that is, had sex during the last three months.
Inof those teenagers who had ever had sex, 18 percent had not had sex in the past three months, 16 percent had it only once a Woman seeking real sex Mott, 25 percent 2—3 times per month, 21 percent once a week, 16 percent more than twice a week, and only 3 percent daily Table 1.
Sex is more frequent among the 18—year-olds than either 15—year-olds or 29—year-olds. Nor does having had intercourse as a teenager imply casual sex, that is, sex with a large of partners or with casual Woman seeking real sex Mott.
According to data from a national sample, about half of all females who have had sexual intercourse have had only one partner Table 1. Although a smaller proportion of blacks 41 percent than whites 51 percent have had only one partner, a slightly larger proportion of white than black teens have had 6 or more partners—9 percent versus 5 percent of blacks. Of course, the of partners is related to the length of time sexually active—such that those who have been active longer have had more partners Zelnik et al.
Adding dating raises the proportion of women in a dating or serious relationship at debut to almost 90 percent, and the proportion of men to over half. That is, only a small proportion of women 10 percent compared to about 2 out of 5 men have first intercourse with a casual partner. The type of relationship with the partner at sexual debut varies by age of the youth. For both males and females, the younger the age at debut, the more likely the first relationship was of short duration recently metof friendship rather than romance Table 1.
In the largest proportion reported that first intercourse occurred in the home of the partner; the next largest proportion reported that it occurred in the respondent's home or the home of a relative or friend. One issue of importance is the extent to which initiation of sexual intercourse is voluntary or involuntary, such as a result of rape or incest. This is especially important for the very youngest teens.
Unfortunately we have no reliable information at the national level. The model of the initiation of intercourse used in this paper builds on models from Udry, ; Fox et al. There are two major components or factors in the model: On the left is the biological component, on the right the psychosocial component.
Interaction between the two sides is represented by the double-headed arrow connecting the biological and psychosocial processes Figure 1. Those aspects of development that each individual experiences are included here. This includes characteristics of the larger society that affect individuals through membership or residence in certain groups or communities. These include the cultural patterns of the broader society e.
Race, ethnicity, social class and religion also constitute reference groups. These contexts represent different societal norms and values which affect the values, norms and beliefs each individual holds, including those of sexuality and fertility. The school and the media also represent contexts. The school affects the educational experiences and levels of achievement of young persons. The media may represent a leveling influence since the national networks provide uniform influence across cultural groups and settings. Probably the most important influence on children is their family of origin.
There are many aspects to the family that could affect sexual behavior: 1 The education, occupation and income of parents, the parents' own family background, and parents' age at marriage and first birth; 2 The of parents in the family, the of children, the presence of other family members; 3 Family experiences, such as divorce or separation, and the interactions among family members, including degree and effectiveness of communication. Finally, 4 the attitudes, values and norms of family members are important aspects of this context.
It is often assumed that during adolescence the family as context for socialization declines in importance and the peer group increases in importance.
Included under peer group here are the values and attitudes of ificant others e. Socialization emphasizes the interpersonal content of learning; development emphasizes the individual Woman seeking real sex Mott of learning. They reflect concepts developed in two different fields: sociology and psychology respectively.
The overall process is one that involves learning. There are several important mechanisms of learning:. Direct verbal communication. This includes information provided by the media magazines, books, popular music, television, etc as well as conversations with parents and friends, and direct teaching in schools, churches and other institutions.
This includes direct and indirect rewards for proper or appropriate behavior and sanctions for violation of behavioral standards. Rewarding desired behavior and punishing undesired behavior are the most direct methods of socialization. However, they are not the only methods.
Children appear to learn the behavior of models without actual rewards and punishments. Not all elements of behavior are copied, and some models are copied more than others, especially those in control of desired resources. Internalization of norms and values. Children learn rules, norms and values, which they take as guide to their own actions.
They may also include strongly held beliefs such as moral disapproval of sex outside marriage. The of this process are conceptualized as the personality of the child, that is, the set of attitudes and values that make up the individual, as well as his or her physical and cognitive capacities and psychosocial characteristics such as self-esteem.
These physical, cognitive and social aspects of the individual determine his or her utility or reward structure, i. This incentive structure is what subsequently determines behavior in a particular situation. The final aspect of the model is that of opportunity and access to alternatives.
The individual may be predisposed by the earlier part of the model to act in a certain way in a certain situation, but if that situation never arises, neither will the behavior.Woman seeking real sex Mott
