No, you put words in my mouth. I'm not implying that I'd rather be married to a man who's good in bed, than one I loved. The two can, and usually do, go hand in hand. I'm sorry that that your naivety doesn't allow you to see that yet. Nor, did I say, that marriage was only about sex. You might not be able to see it now (seeings as how you've neither had sex, nor are you married - both major components you'd need, to understand this concept, apparently). But it IS important. That intimacy will become an important part of your marriage.
And I can tell you from experience, you might think the sex is going to be good no matter what just because you love each other .. but that is NOT always the case. Come back after you're 'happily married' but unfulfilled in the intimate part of your life because your husband can't give you an orgasm, and try and tell me that you could go the rest of your life like that just because you love him. VERY few people can do that, without cheating. I hope, for your sake if that ends up being your case, that you can. Good for you if you can. *shrugs*
I am very much in love with my husband, and he with me, but that doesn't mean that sex isn't important. Love-making is a very solid part of our foundation. My comment about 'taking a little heartbreak first' doesn't IMPLY anything. It's simply stating that ... if what you said is true (and obviously isn't, I'm proof) I'd rather take my risk of heartbreak because I had sex first and break up later, then be unsatisfied later in life in my marriage. You can't -possibly- understand the effect that sex has, since you haven't had it.
It's utterly ridiculous for you to bother trying to argue that it won't be important.
You are very right on one point. You are 17. Sex should not be a top priority for you - and I'm very glad for you that it is not. You are above most girls your age - you should be proud. At your age I was already pregnant with my first daughter. I just got lucky and we're all one big happy family. *shrugs*
