Biblically speaking, being sexual aroused is no more lust than it is to become hungry at the site of a food commercial on TV. Sexual arousal is not a curse, but a gift from God. Too many Christians and Churches throughout the centuries have treated sexual arousal as burden of the flesh to be overcome when it is not.
Food and Sex actually have a lot in common
Both food and sex are necessary for the continuation of the human race. If just a few of us stopped eating, then the human race would not die, but if we all stopped eating then the human race would eventually die. In the same way, while none of us would die from not having sex, the human race would go extinct if we all stopped having sex.
Another interesting parallel between sex and food is how variety affects pleasure. Let’s say your favorite food is a cheese burger from a local burger joint. If all you could eat was that burger from that restaurant, and never eat any burger from any other place, or any other food eventually you would become bored of that food. Would it sustain you? Yes. Would it give you the same pleasure it once did? No.
It is exactly the same when it comes to human sexual arousal. Having sex may give us some relief, but without variety it soon begins to lose its pleasure. That is why it is so important for Christian married couples to keep variety in their love lives. What that means for each couple will be different, but if you do things the same way every time your sex life will eventually become stale.
