Lust is not caused by hormones. Jesus had the same hormones you do, and He never lusted. Sexual attraction is physical, and is good. Lust springs out of a spiritual origin, the sin-nature, and is bad. That's why the Spirit of God can lead us into victory over lust. To lead us into victory over sexual attraction would require God to de-humanize us. But lust is a spiritual impulse, and so, as a spiritual impulse, it can be overcome by the Spirit.
