To add a bit to what AlexEliezer wrote:
Obviously sexual desire is a normal thing that every healthy male experiences. More than that, it's the strongest desire as well (as written in many Torah sources). Nobody's asking you to suppress or eliminate it, that would be unhealthy and possibly close to impossible. What is asked from us is to have a healthy sex life, just as you wrote your goal currently is. Here's where it gets thorny though.
The difference between the world's definition of a healthy sex life and the Torah's, is huge. The world's definition is the simple intuitive one, if it isn't damaging, and both parties are happy with it, then it's healthy.
Lehavdil, the Torah's definition of healthy isn't only physical, it also incorporates the spiritual. There are many consequences of this and they're reflected in the Torah's laws.
There are many factors and aspects involved, I'm far from an expert but I'll try to share what I know. Two of the attitudes reflected in the Torah's laws are toward, self control, and toward selfishness.
Self control: Jews need self control in order to fulfill our tafkid on this world. This one reasons for us having to keep kosher as well. We have to control ourselves in all we do so as to be able to keep ourselves involved in higher pursuits than chasing after physical pleasures and desires. Now, the stronger the urge, the more guidelines we need to keep it under control. Hence the strict rules regarding sex in the Torah.
Rabbi Noach Weinberg Zt"l once put it "you can't orgy at night and then learn in the morning, it just doesn't work" (I'm quoting this from memory so the words are probably slightly different).
Selfishness: Our way to perfection is by emulating Hashem, since he is the ultimate perfection. One of Hashem's notable characteristics is chessed. Therefore, the Torah looks at any purely selfish act as something to avoid. So, as AlexEliezer put it, Lust is about me, intimacy with your wife is about us. This is reflected in Halacha numerous times. One example is the issur to have relations after you fought with your wife, since you'd be solely focused on your own pleasure and not hers due to your anger.
As in many, perhaps all, parts of life, when you follow halacha, you not only gain spiritually, but in this world as well. It's a well known fact that having sexual relationships before marriage increases the chance of getting divorced. But leaving that aside, there's a certain satisfaction to be had when living life spiritually, and with you, not your animal desires, in the driver's seat.
