Should all schools have comprehenive sex ed?

I live in an area where they will only teach abstinence. We had a speaker at my high school a couple of years ago and all he spoke about was how terrible it was to have sex before marriage and how if you did, you should be guilt ridden. I had to go to that assembly twice because of scheduling and I was boggled of how many students were eating it up. It was like brain washing before my eyes.
The speaker even spoke against the use of birth control, only emphasizing the risks and not speaking at all of the benefits. He also was suggesting that a condom can fail even though it doesn't break. That somehow, sperm can get through solid latex or lamb skin. If air cannot get through it, sperm sure as hell can't!
So how can we wonder why there are outbreaks of STDs in schools and why so many girls get pregnant?
I believe it is because parents think they are shielding their children when really their children are just learning about sex from their peers and partners. And that information can be very misleading such as to double wrap (allows the condom to break easier), you can't get pregnant with the girl on top (don't even get me started on this), and my favorite you can't get pregnant on your period (sperm lives in the body for a very long time).
No wonder there's a hit show about girls getting pregnant and not knowing- Parents and schools are allowing this ignorance!
I think there should be proper sex education classes.
What do you think?

Same here... I totally agree.
I mean sex education should give facts and useful information. Not an attempt to encourage or discourage teens to have sex, it should give advice to keep healthy if you're having sex. The lessons you just described are trying to prevent teens from having sex, and I bet the people who are giving these lessons are religious.

Sex education in early adolescence has been proven globally to reduce the spread of STI's and unwanted pregnancies. I'm totally for it. Better to learn the facts from an informed, qualified adult than from your imaginative peers and other venues like Wikipedia, porn, or religious zealots.
Of course there is a time and a place for everything. I think preadolescent/grammar school kids are too young. Maybe a course explaining masturbation, anatomy, and sexual abuse in gentle terms for this age group would be appropriate, but not much more.

"I have a problem that parents and society leaves it up to the schools to teach kids about sex, shouldn't that be done at home, just another parental cop out...."

It would be great if there was a [required] parental orientation at grammar/middle schools for parents to attend and learn how to approach the topic of sex with their kids, since I agree it's best for kids to get the facts from home. Parents should be teaching their children values and safety in all departments.

Here is how I approach the topic of sex with my daughter, she asks, I answer. In the same instance, if I notice there is something she needs to talk about, I talk to her. Most parents prefer to bury their heads. All aspects of sex should be taught, in the home and in the schools.

"bob shank"-
I appreciate your sarcasm however I merely thought that it was obvious that abstinence is of course the only true way to avoid stds and unwanted pregnancies.
And some parents simply refuse to teach their children about sex as thoroughly as they should, laddle on the guilt and create complexes for their children for later on in life. That's why it would be better for trained perfessionals AND parents to teach sex.
AND
yes "dark secrets" that persentation at my old school was connected to religion. The mesa az area is a popular mormon location.

I guessed that because of many things. which is why I added that in Bob. I live in a religious community and I am religious myself. It is just that some people take religion literally in these aspects. I guessed they were religious not only because they don't want their kids having sex. But because they added things like "before marriage" into it. I guessed they were religious because they recommended them not to use birth control if they are having sex (and I have heard this on and on with religious people). Being religious doesn't make a person ignorant, taking things literally and trying to convince others with what you don't understand is.

I think if sex is taught in these kind of communities people should form a commity of diverse people with different knowledge, so they could get the right message to people, and put in a little lecture for religion. Because not all religious people believe or follow the same traditional ideas about sex.

I don't think I ever got "the talk." From my parents it was "don't come home pregnant," and from my school it was "here are all the different STD's you can get, and what they will do to you." All I remember from church was learning that our youth leader had sex seven times on her wedding night. Fortunately, I've always been a curious little individual, and did my own research. (Not experimentally, you guys.)

But yes, yes, yes they should teach sex ed in school. It would be wonderful if all parents would do it themselves, but hey, it wouldn't be the first time that schools become responsible for civilising some kids. It's been shown again and again: while, sure, abstinence works, abstinence-only education does NOT.

Basically all I think is sex ed should really include that: sex information. If all that is being taught is abstinence, it should be called that.
A mixture of both, taught in high school, when most kids are beginning to dabble into it, would be more helpful than just abstinence.
And those who are lecturing waiting until marriage because of things such as losing a child to AIDS than they should be talking about condoms as well.
That is the responsible thing and they should be talking about other ways of avoid passing AIDS other than abstinence and how to be responsible of you and your community.
Also, research of the AIDS outbreak has shown that a lot of the cases were brought on by unprotected sex. Condoms can really save lives. But this is all my teenage opinion and what I am experiencing now.
**AS A SIDE NOTE: THOSE WHO ARE SEXUALLY ACTIVE SHOULD ALWAYS GET CHECKED ANNUALLY OR ANY TIME YOU HAVE SEX WITH A NEW PARTNER. LADIES, DO NOT PUT OFF THOSE YEARLY PAP SMEARS. THEY CAN PICK UP A LOT.**

". . . guys be wary of those who give you condoms, these days kids want kids and think that will lock you down to them forever, and young ladies just because you see him putting the condom on doesn't mean he's wearing it throughout . . . "
I agree with this completely. It is true on both ends. And I also agree on this opinion-
". . . as a side note, I am totally against waiting for marriage before intercourse, suppose you aren't physically compatible, that would make for a very miserable marriage. . . "
But I do feel that your first time having sex (both ever and with someone) should be something with meaning and love.
I also think that this is something that children get to think about as well as other (perhaps more important) questions if they are taught in advance.

^That's just scary. When I was 15 I didn't even want to kiss anyone. I mean, I was probably a late bloomer, but still!

I mean... I guess people used to do it all the time. If you were fertile, you were good for babymaking. But with our extension of childhood and adolescence in this time, I can't imagine it would be anything but terribly difficult. Mothers now are expected to be knowledgeable in more things than cooking and childrearing, and those sorts of wisdom take a while to develop. Plus, if you want higher education, need to work for your rent, etc.... rough.
