You used moral as an adjective in you post. Since pre marital sex is widely considered wrong conduct, which one were you referring to?
1. of, pertaining to, or concerned with the principles or rules of right conduct or the distinction between right and wrong; ethical: moral attitudes.
2. expressing or conveying truths or counsel as to right conduct, as a speaker or a literary work; moralizing: a moral novel.
3. founded on the fundamental principles of right conduct rather than on legalities, enactment, or custom: moral obligations.
4. capable of conforming to the rules of right conduct: a moral being.
5. conforming to the rules of right conduct (opposed to immoral): a moral man.
6. virtuous in sexual matters; chaste.
7. of, pertaining to, or acting on the mind, feelings, will, or character: moral support.
8. resting upon convincing grounds of probability; virtual: a moral certainty.
Obviously, I dispute that premarital sex is wrong conduct, and I dispute that it is widely considered wrong conduct.
Lets take the second point first. I think a majority of people under 25 don't even consider oral sex to be sex, much less immoral. And I don't think the notion that sex out of wedlock can be moral is restricted to young people. I would even bet that today a majority of senior citizens don't consider sex between senior citizens neither of whom is married to anybody to be immoral. So I think you are way out of touch with popular opinion.
More importantly, I don't think there is any reason to believe that sex out of wedlock is wrong. I think that an ideal life includes plenty of premarital sex. And I don't consider myself a hedonist, either. I think that people who marry as virgins have far more regrets on their deathbed than people who behave morally. Rules that may have been appropriate before condoms and penicilin and women in the work force are just outdated.
Let me guess: you are a teenager?
