i don't see why it is ironic to have sex after you marry. and, i don't think chastity is taught in school as of equal value to contraceptives. there are more reasons than just STD's.
It's ironic because people are blamed for having sex before the nuptual event, labelled as sinners, and then just after they marry they can all of a sudden have sex all they want. Aside from legal factors, how is a married couple in any way physically different than a non-married couple? The school doesn't need to teach chastity, it teaches the ramifications of sex. Schools need to give facts. It is religion that tries to impose chastity and the maxims of sin.
for one thing - don't men assume a woman loves them if they are willing to have sex with them - and visa-versa. and, don't men assume a kind of 'ownership' - whether they admit it or not and prefer not to see other men with 'their woman.' so - it's really a big lie to say that virginity is nothing and yet consider the 'oneness effect' (which i think is mental and comes from God) to be important enough to shoot another man over or pound the girlfriend into oblivion. or, as with others - murdering both parties.
No, men assume that if a woman is having sex with them, then they aren't going to have sex with any one else.
if you want to see the worst in human nature - get involved in sexual indiscretion. i think that's what most movies are based on. the side of human nature that gets jealous. why this jealousy? could it be pre-programmed by God into men and women - for the properties it has for keeping a family intact. unless, of course, all the consenting people are swingers or something - and really don't care.
Intrinsically, there is nothing wrong with having many sexual partners. The down side is of course moral considerations. Jealousy, as well as all other human emotions are natural to humans.
that is an animals mentality, imo. civilization brings with it laws and responsiblity. you don't have to keep the laws. you don't have to be responsible. but there are natural laws that just don't like being broken and i think people get the consequences by their own hand.
The natural law is to have sex with whoever you want. It is the way animals reproduce, and this type of promiscuous behaviour isn't controlled by logic. If no laws existed, and humans weren't conditioned to keep fidelity, most men and women would have many partners during their sexual career.
what if two people are young teens and can't get enough because parents come in between and only let them have it when they are gone on vacation. are the two going to stay faithful to each other once they have experienced sex? i don't know. perhaps it depends on their maturity. but, the other side of it - is that if they have a baby - the baby is a bastard unless they marry. do you want your children teased or fatherless completely? that would be sad.
If teens want to have sex, I see no reason to stop them. As long as they are educated in these matters, and know how to behave responsibly, I don't see how sex can harm them.
