Sparky: true, i can't speak with my own authority. but i draw my conclusion based on several things:
numerous reports of it from friends who waited prove that this is true;
the fact that promiscuity (which is almost inevitable when a person doesn't know how to/can't restrain and control themself) ruined so many people's lives simply because sex became too casual. psychology states that we, humans, often use sex to either get the things we want or to feel we're in control when some other area of our life has gone completely out of hand. and couple and marriage therapists say that sex is only the main thing that keeps a couple together for the first three years. after that you have to have some solid base for your relationship other than sex. here i agree with Zekk on the point that sex is sacred and is designed for love for sure. i take it to the next level - i think it's designed for marriage. but, to get back to my second point, when you start having sex before marriage, the flaw is obvious - you start sex sooner and your "sex" motivation fades quicker. by the time you want to get married it's either because you're really in love or you just don't want to bother to find someone else when this person here "will work for me". and that goes into the next point, which is my best argument:
when you start making love/having sex early on, you shut out all other aspects of the relationship. we, humans, are such that we get stuck on the physical side. once we start, we can't stop. and we can't stop thinking about it. and we don't get to know each other's personalities as well as we could have. my point is: first really get to know the person, explore them emotionally, find out much about what a person they are; and then, when the time is right (for me personally that means marriage - you've really proven that you're up for the commitment), you get to explore the other, very gratifying aspect of the relationship. but you have to be able to make your soul primary - don't let Freud be right in saying that, well, "it's ALL about sex". cause it isn't. but it can easily become all about sex when you let your basic instincts override your humanity. that's when "you and me, baby [become] nothing but mammals".
