"Unfulfilling Life"
by these I assume you mean living a life of sin as lusting after physical satisfaction every day, because it's your body and you can do what you want with it...
where I believe that my body is something given to me by God, and I should take care of it... and living a Godly life is much more rewarding than lusting after our desires...
also God is less offended by physical sin (Lust, Gluttony, etc)
here is some lists to consider before claiming that living virtuous is "Unfulfilling"
THE 7 DEADLY SINS
Lust – to have an intense desire or need: “But I tell you that anyone who looks at a woman lustfully has already committed adultery with her in his heart” (Matthew 5:28).
Gluttony – excess in eating and drinking: “for drunkards and gluttons become poor, and drowsiness clothes them in rags” (Proverbs 23:21).
Greed - excessive or reprehensible acquisitiveness: “Having lost all sensitivity, they have given themselves over to sensuality so as to indulge in every kind of impurity, with a continual lust for more” (Ephesians 4:19).
Sloth – disinclined to activity or exertion: not energetic or vigorous: “The way of the sluggard is blocked with thorns, but the path of the upright is a highway” (Proverbs 15:19).
Wrath – strong vengeful anger or indignation: “A gentle answer turns away wrath, but a harsh word stirs up anger” (Proverbs 15:1)
Envy – painful or resentful awareness of an advantage enjoyed by another joined with a desire to possess the same advantage: “Therefore, rid yourselves of all malice and all deceit, hypocrisy, envy, and slander of every kind. Like newborn babies, crave pure spiritual milk, so that by it you may grow up in your salvation” (1 Peter 2:1-2).
Pride - quality or state of being proud – inordinate self esteem: “Pride goes before destruction, a haughty spirit before a fall” (Proverbs 16:18).
