The Difference Between Lust and Sexual Desire

There are 613 laws in the Torah. None of them say do not lust. You don't lust after a house or a donkey, right? One presumes. And yet you're not allowed to covet those either. But do you make a distinction between sexual desire and lust? Do you see a distinction? No, I don't. If they weren't different things, we wouldn't have two separate words for them. Right. Also, which comes somewhat of a revelation to my Christian friends is there is no, there is no sin of this.
