are unmarried when the child is born. For 85% of recent college 
students it wasn't considered important to marry a virgin. Today's 
young wives are also more unfaithful than their mothers or 
grandmothers were, almost as unfaithful as today's young husbands 
(Sex, before and after, 1975). The sexual revolution has brought many 
other changes: fewer prostitutes, earlier intercourse (average 
age=16), more experimentation (different positions, oral-genital 
activity, sex with drugs), more partners, higher frequency of sex, more 
orgasms for women, and more living together.  
The sexual activities of teenagers has also changed significantly over the 
(
general information, and advice to parents and teenagers about teen sexual 
behavior. It is a conservative site but not overly-moralistic. It attempts to 
clarify the difference between "normal" sexual activities and "dangerous" or 
risky behaviors; thus, avoiding the unrealistic "just save yourself until 
marriage" message. The same site also has a section about teenage 
emotional health. Other very explicit and liberal (parents may want to check it 
(
suggestions about many topics, such as Abstaining, "Sex by Yourself, "The 
First Intercourse," Waiting till Thirty, etc. These sites are also good places to 
see what kind of questions todays teens have and the advice they get and 
give on many topics (see discussion groups).  
The AIDS revolution is also having some impact on sexual 
behavior: surveys of high school students in grades 9 through 12 show 
that slightly fewer (55% rather than 60%) have had sex in the early 
1990's than in the late 1980's. Also, fewer high schoolers (20% rather 
than 25%) have had four or more partners. The fear of AIDS and sex 
education may be having some effect, but still only somewhere 
between 17% and 40% of the sexually active high schoolers use 
condoms regularly. Unfortunately, the teens with the most partners 
are the least likely to use condoms--and the most likely to shoot up 
drugs. In short, if you have sex in high school, the probability is about 
50-50 that your partner has already had sex with someone else or 
shot up drugs (don't trust what they tell you) and, thus, could be HIV 
positive. Moreover, one out of every 25 high schoolers has a sexually 
transmitted disease (and the person "coming on" to you is even more 
likely to be diseased). Therefore, even at a very young age, if you are 
going to have intercourse (even with a supposed virgin), use a 
condom. It may save your life (not to mention pregnancy and 
disease).  
The first sexual experience comes early: 40% of 9th graders have 
had intercourse, 48% of 10th graders, 57% of 11th graders, and 72% 
of seniors. The first experience is memorable for everyone but for 
young teenagers it frequently is not fun, particularly not for the 
female. For one thing, most of the time (78%) intercourse is not
