I do have desire for sex, but once again, with WHO? Yes, of course romance and sex can still be pleasurable, I like reading romance novels and watching Hallmark - as a straight man, believe it or not, but that's just that, pleasurable fantasies between fictional characters. I'm wise enough to know that I'm just an observer, I don't picture myself in these fantasies.Well, sure, we can have unrealistic fantasies about romance or sex. That doesn't change the fact that romance and sex can still be pleasurable. That's one of the reasons many of us want it so badly. Nothing wrong with that.
The Bible does not condemn sex or sexual desire. There's sinful ways to have sex, yes. But sex between a married couple is what the original norm was. It's good, and it's supposed to be good. That's how God designed it. Are fornication and adultery the only possible ways to have sex?
And do you mean that you, personally have no desire for sex? If so, well, great. Good for you. Not everybody's like that. For you, they're abstract. For others, not so much. Some people have strong desires for sex. That's fine.
You seem to think that romance or marriage is inevitably doomed to failure. If so, I find that puzzling, to be honest.
And I'm not saying that "romance or marriage is inevitably doomed to failure", I'm just reminding you and everybody else, that this relationship progress is not an escalator, but a rock climb. If you're with somebody who's practically just a stranger or a mere acquaintance, yet in your mind she's already your wife and you feel you're entitled to her body for sex, based off of your justification of wanting sex "so badly" as a natural desire and a part of being human, then I'm afraid that is indeed inevitably doomed to failure, it would only leave you hurt and anguished, and probably that somebody as well.
