We all know that "lusting" is bad for us, spiritually and physically. It destroys lives and takes the person away from his life's goals. We all know that there's really nothing there, and that it's all a big bubble of hot air that pops in our face. So why should we let the body rule over us, just because our brains are "wired" in a certain way?
The Tikunei Zohar writes "Happy is the man that controls his evil inclination like a rider on a horse. Woe to the man that the horse rides him!"
