Oral sex leads to other sex for teens

Oral sex is often a precursor to teenagers having intercourse, concludes a new study published in Archives of Pediatric and Adolescent Medicine. The study asked more than 600 high school students in California to report on their sexual experiences by filling out surveys twice a year, from the beginning of ninth grade, in 2002, to the end of 11th grade, in 2005.

From the questions asked on the survey, and the six-month window in between each one, researchers learned that most adolescents have their first experiences with oral sex and vaginal intercourse in the same six-month period. They could not extrapolate which experience came first but discovered that among teens who initiated only one of the two types of sex during that six-month window, oral sex usually preceded vaginal intercourse. Additionally, having oral sex once made intercourse more likely to occur. Specifically, initiating oral sex by the end of their freshman year in high school gave teens a 25 percent chance of initiating vaginal sex around the same time and a 50 percent chance of initiating intercourse by the end of their junior year. The results of the study did not vary across any racial, ethnic or gender boundaries.

The goal of the study was to establish the relationship between oral and vaginal sex and whether teens used oral sex as a means of delaying intercourse or if oral sex increased the likelihood of having vaginal sex. The study found the latter to be true, partly because most adolescents don't consider oral sex to be sex in the first place.

"We don't talk about the risks that are inherent in oral sex," says Bonnie Halpern-Felsher, Ph.D, senior author of the study and a professor of pediatrics at the University of California San Francisco. "Teens think oral sex is less risky [than intercourse] and they're right, it's not risk free but it is less risky. But socially and emotionally, they're still being intimate."

Halpern-Felsher believes teenagers are most likely to initiate oral and vaginal sex during their first two years of high school. She advises concerned parents to talk to their teens about oral sex and not focus solely on the risks associated with intercourse.

"We have a disadvantage as health professionals and parents when teens do not equate oral sex with sex," says Halpern-Felher. "They think the messages don't apply to them and we need to make it apply to them, we need to talk to them about oral sex."

    So lemme get this straight...oral sex leads to intercourse? Um...I SURE AS HECK HOPE SO!!!! I'm glad teens are smart enough to learn foreplay! At least maybe future generations won't be so lame in bed if they know the basics.

    My parents taught me abstinence. I lost my virginity at 13 in 1998 because I couldn't stand their right-wing roman catholic ways. Kids have sex. Teach them how to do it safely. I'm now 26 and have a 2-year-old (and in a wonderful committed relationship with my middle-school sweetheart) and you best believe that I won't be one of those naive parents who's shocked when I find out my child is no longer a virgin. Teaching abstinence is great, but we need to also give them information on ways to protect themselves if they choose to have sex. Obviously it's best if they refrain from it, but they're teenagers and they're going to do what they want. The least we can do is educate them. My parents didn't; thank God for public school for teaching me about condoms or I could have a child half my age.

    I can't understand why researchers who do these idiotic studies continue to confuse correlation with causation. These two acts (sex and oral sex) are correlated. That does not mean that they are causal. This type of study is ill-conceived and the purported "results" are misleading.

    It makes sense. It's like drinking your first beer. People pressure you, you say no, but after months or even years, you give in. Because the stigma is now gone, the next beer seems like no big deal. This would apply to anything, including sex. How many of us wanted to wait until marriage, but didn't? And once that was gone, no sense in turning it down next time.

    The best thing you can do for your kid is EDUCATE them so they can make informed decisions about stuff like this. When my mom found out I was having sex as a teenager, she didn't freak out or yell, she knew I was using condoms but also took me to get on birth control, and just sat down and talked to me about the risks. Of course as a teen I just rolled my eyes and said "whatever" but it did mean a lot to me that she didn't get angry with me or make it seem like it was something "wrong" and her caution stuck with me.

    Abstinence-based education does NOTHING because it's not telling teens about condoms and birth control and ways they can protect themselves if they make the choice to have sex. It makes sex seem like a shameful thing so they are embarrassed to buy condoms or make any outward association with the fact that they are having sex. So they'll do it unprotected because of ignorance or shame and end up with an STD or a kid way before they are ready. Abstinence education is doing the exact OPPOSITE of what it's intended to do. Stop fighting mother nature, she gave us those teenage hormones to be used.

    Angry Carolyn is right. Those teens taking a sex questionnaire would find more pleasure in creeping out the moral majority than admitting to being a virgin......How embarrassing. To get real responses.....well, real or real sarcastic, real stupid, or really off subject, etc....Just glance over all the responses of anything CNN reports.

Most of whom have outstanding loans from University, money that 'employed people' as well? Geez. Maybe if you'd take your head away from that blow job, you might learn something useful.

    I can't really say that oral sex led to vaginal sex back when I was a teen in high school, Hell if I remember correctly back in the 1980's when I was a teen,which to me (( Were by FAR the GREATEST years of ALL to have been a teenager )) I tried and tried to get most all of the girls I did get LUCKY with to perform oral sex before vaginal sex,But hey there wasn't gonna be any of that, But if you look closely I did say MOST of them,There was the occasional LUCKY BREAK!!! But to be totally honest with you as a guy back then I didn't particularly care to have my lady friends perform any oral sex, Don't misunderstand by any means I really really loved all the foreplay,Heck thats what led up to all of the sure enough good play. But I guess now days here in 2010 from what books I read ( Playboy,Hustler,and some other adult books ) I do see that the majority of High school,And college age young women may prefer to perform some type of oral sex in order to keep from engaging in vaginal sex,I would have to say in order to maybe keep from getting pregnant,or just maybe to just not have vaginal sex because they don't want to lose their virginity. If one is engaging in oral sex with a guy or even another female,It's certainly not to keep from getting any diseases, Because you can get diseases by performing oral sex as well as vaginal sex ladies,So don't fall for that old trick if your a little on the nieve side. All I can say is please be extra extra careful when you do decide to have sex of ANY kind. As the father of a teenage daughter and a son that is coming of age as well,I am very very fearful of what may be lying in wait for one or the both of them if they are not particular about who they choose to do things with. But as I said PLEASE be careful when you do have ANY type of sexual contact make sure you know the person well enough to know if they are clean and safe to put you life into their hands because it only take ONE time <and life as you know it could go down the drain in less than the blink of an eye...(( for some folks that is ))

      I am one of these so called girls you all are talking about. I have had a promise ring (to stay pure till wed) since I was in 6th grade. Once I got into highschool I dated my first real boyfriend for 3 years. Never did we have sex but yes, some oral sex was there. This boy cheated on me many times near the end loosing his virginitiy to a girl that attended the school. So, maybe girls think they need to do things with their boyfriends or just one night stands not to loose them.

    I am a teacher at a LOW performing school. All of you idiots who are "Okay" with teen sex need to come to my classroom and observe the kids I have with single parents and the kids I have who were from teen pregnancies. They are mostly all getting F's and D's because both parents made a teenage mistake and don't have the money or the care to raise these kids right.

    I think people forget thats sex makes babies–wait a minute, I don't think the public really cares since our abortion rate is about 1,000,000 infants a year. http://en.wikipedia.org/wiki/Abortion

      No one is saying "yeah let teens do it all the time". Were just saying, they are going to regardless. So why not give them all the information and things they need to reduce the amount of teen pregnancies. Telling them "No" isn't going to stop them. So give them condooms and other forms of birth control so they are informed instead of sneaking around and doing it and accidentally getting pregnant.

      Really man? Whether I am OK or not OK with teens doing what they are going to do is irrelevant...I just heard you say that home life is crap, there is a high liklihood that the parents are totally ignorant and not involved..... So you think that teens having sex is the cause of all that? Don't think there isn't some other factors coming into play there? You're focused on the end result not the drivers.

    This is why after High school anyone with a clue would read, research, or travel, as opposed to say, going to school for another 8 years to study oral sex and the effect of potato chips on fish. This is sad, hope we are proud. Won't find me wasting my life's years to learn absolutely nothing. Enjoy that.

    "In related news, additional funding has been approved to draw conclusive proof that the sun does rise daily and that water remains wet.
    Seriously, what the hell. Kids experiment with sex. It's how the species works. Give them information & knowledge. Give them tools and clue. Then give them a little privacy."
    See this is the problem with the society we live in today. This type of argument is usually posted by someone who does not have children or is a child themselves. Hurry up and grow up you only have 80 or 90 years to live. Everybody is in a rush to grow up and do the things the "big people" do.
    Look, I teach middle school and the students are all about privileges but don't want any of the responsibilities associated with those privileges. I have watched holiday dances morph into the prom in middle school (why wait, huh?) I have overheard students talk about movies they have watched that they had no business watching (they are neither mentally or emotionally ready for the subject matter) . Just because their bodies are adult size doesn’t mean their minds are.
    Too many parents have abdicated parenthood in favor of friendship. Mommy and daddy or mommy and her boy friend(s) or daddy and his girlfriend(s) do it, you should too. Oh, and don’t worry the tax payers are more than happy to pick up the tab on your mistake.
    It’s hard enough to raise kids in a stable relationship much less as a young, single, uneducated and for that matter unemployed young person. But I guess everything will be all right as long as you “give them tools and a clue. “
    How many babies have died (either through abortion or abuse and neglect) because of this ignorance? Remember just because you have the right parts and they are mature doesn’t mean you should use them.

    Actually I think this is a valuable study. There is growing perception in the parent world that kids these days use oral sex as a substitute for sex–so they don't have to worry about pregnancy, STDs, etc. That kids will now have "oral sex parties" where the last generation of adolescents had "make-out parties." Even though a conservative parent would still be horrified at this, there's probably still a tendency to think "well, at least they're not having sex and I don't have to talk to them about it." This article/research debunks that thinking on two different levels. First off, oral sex IS sex and still has risks worth talking to your kids about. More importantly, it seems, the perception is incorrect anyway. Sure, maybe these days kids are more likely to start their sexual careers with oral sex (I don't think that was always the case), but that's only the "gateway drug," so to speak. So either way, parents ought to talk to their kids about sex, period.

    Like, duh! But the REAL question is : do kids use condoms when having either form of sex?! Oral chlamydia, gonorrhea, syphilis, herpes, are all disgusting and can be M.D.R. strains (Multiple Drug Resistant), causing a VERY expensive and embarassing visit to a clinic or doctor's office.
    When will we wake up from our Puritanical & hypocritical stance on sexuality?! Probably never. But it might help if we take the Victoria Secret shows out of a prime-time viewing slot? I think not. WE [adults] know "sex sells – everything".
    Comprehensive sex education and the de-mystifing of the female AND male genitalia "might" help. Breasts are simply over enlarged sweat glands and the penis is for excretion. There! Now, ain't that sexy???

    I was 14 when I did the deed in 1990. I can't remember if there was any oral as a precursor. Puritans went away for a reason. Information and education within reasonable boundries is key. Don't think your kids don't know what you're up to when the bedroom door is closed. Leave them to figure things out on their own and you are doing them a disservice. Part of being a parent means addressing situations that aren't always comfortable for you.

    So after reading about 31.8% of the comments I must admit that yes, to the average, slightly intellegent adult this case study is irrelevent, for it is stating the obvious. But for the non average adult, i.e. someone who doesnt believe in vaccinating their infants and that a good herb is the cure for everything, this study is a way to provide Irrefutable, concrete evidence supporting the hypothesis of the researcher. The scientific method (which I assume everyone learned in junior high) has concrete steps that must be followed in order for an idea to become theory. And I think that is the main goal of the resesarcher. In order for the scientific community to accept an idea, there must be recorded facts. And that, dear Watson, is the rub. I'm sure that for every teenager that said yes, there were 4 that said no. It's not the results that we need to question, it is the method in which they were collected and analyzed. If I polled my high school right now, I could probably obtain two totally contradicting results.

    As for teenage promiscuity......they're gonna do what they wanna do. There isnt a sure fire way stop them, but providing information is a step in the right direction.
